All the parameters which can be set in quick programming mode are also displayed and can be set in the advanced programming mode.
Setting Examples The following points are examples of settings for applications. Page Adjustment Suggestions Adjustment Suggestions If hunting, vibration, or other problems originated in the control system occur during trial operation, adjust the parameters listed in the following table according to the control method. This table lists the most commonly used parameters only. Page Table 4.

The gear ratio Adjustments U shoes the kWh Lower lower four digits, U 4 dig Current Fault Last fault U The content of the last fault.
The format is the same as for U Page V and V Class Inverters of 0. The setting ranges for the Inverter carrier frequency, overload capability and maximum output fre- quency depend on the setting of C The setting ranges and factory settings of some parameters change with the setting of C Page Carrier Frequency and Inverter Overload Capability The inverter overload capability depends among other things on the carrier frequency setting.
If the carrier fre- quency setting is higher than the factory setting, the overload current capability must be reduced. If the carrier frequency is set to a higher value than the factory setting, the overload capability is reduced like shown in Fig 6.
When terminal S3 multi-step speed command 1 is OFF, terminal A1 input master speed frequency refer- ence will be the Inverter frequency reference, and when terminal S3 is ON, terminal A2 input auxiliary speed frequency reference will be the Inverter frequency reference. Page Using Multi-Step Speed Operation Using Multi-Step Speed Operation The inverter supports a multi step speed operation with a maximum of 17 speed steps, using 16 multi-step fre- quency references, and one jog frequency reference.
The following example of a multi-function input terminal function shows a 9-step operation using multi-step references 1 to 3 and jog frequency selection functions. Page Setting Precautions When setting analog inputs to step 1 and step 2, observe the following precautions.
When setting terminal A2's analog input to step 2 set H to 2 auxiliary frequency reference. Page When Closed Loop Vector control is selected, the stopping behavior depends on the setting of b Analog frequency E reference The Run command turns OFF and zero speed control starts when the motor speed feedback drops below b The applied DC injection current can be set in parameter b The DC injection braking time depends on the set value of b and on the output frequency at the moment when the stop com- mand is input and.
Set parameter b to apply DC injection to the motor, before it starts to accel- erate. The time chart for the DC injection brake is shown below. If inputting the fast stop with an NO contact, set the multi-function digital input termi- nal H1- to 15, and if inputting the fast stop with an NC contact, set the multi-function digital input terminal H Page Time Chart The following figure shows the frequency characteristics when L is set to 1.
The acceleration rate is lowered. The acceleration is stopped to reduce the output current. Time Fig 6. Page Preventing Overvoltage During Deceleration Preventing Overvoltage During Deceleration The stall prevention during deceleration function lengthens the deceleration time automatically with respect to the DC-bus voltage to avoid overvoltage tripping. Page Setting Example An example of stall prevention during deceleration when L is set to 1 is shown below.

Page Adjusting Frequency References Adjusting Frequency References Adjusting Analog Frequency References The analog reference values can be adjusted using the gain and bias functions for the analog inputs. Page Refer to Fig 6. Frequency bias Multi-function analog input terminal A2 channel 3 input Related Parameters Control Methods Change The digital multifunction outputs M1 to M6 can be programmed for this function and can be used to indicate a frequency detection or agreement to any external equipment.
Page Time Charts The following table shows the time charts for each of the speed agreement functions. The slip compensation func- tion keeps the motor speed constant, regardless of changes in load. The setting value of C depends on the control method.
Fig 6. Operate the motor at zero speed. Increase C ASR proportional gain 1 to a level where no oscillation in the motor speed occurs. Decrease C ASR integral time 2 to a level where no oscillation in the motor speed occurs. Page Different Gain Settings for Low-speed and High-speed Switch between low-speed and high-speed gain when oscillation occurs because of resonance with the mechanical system at low speed or high speed.
The gain and integral time can be switched according to the motor speed, as shown in 6. See Fig 6. Page Hunting-Prevention Function Hunting-Prevention Function The hunting-prevention function suppresses hunting when the motor is operating with a light load. It calculates the amount of speed fluctuation using the torque current Iq feedback value and compensates the output frequency with the amount of fluctuation.
The torque limit can be set as fixed value using parameters or as variable value using an analog input. The table below shows the possible analog input settings H for the torque limit function. The torque limit has the priority. Page Motor Torque Detection Motor Torque Detection If an excessive load is applied to the machinery overtorque or the load drops suddenly undertorque , an alarm signal can be output to one of the digital output terminals M1-M2, M3-M4, or M5-M6.
Page L and L Set Values and Operator Display The relationship between alarms displayed on the digital operator when overtorque or undertorque is detected, and the set values in L and L, is shown in the following table. The induction motor's cooling abilities vary with the motor type. Consequently, you must select the electronic thermal protection characteristics.
Set L to: 0: to disable the thermal motor protection function. The thermistor must be connected to an analog input. Page Automatic Restart Automatic Restart This section explains functions for continuing or automatically restarting inverter operation after a momentary power loss. Restarting Automatically After Momentary Power Loss If a temporary power loss occurs, the inverter can be restarted automatically to continue motor operation.
To restart the Inverter after the power has returned, set L to 1 or 2. Page Speed Search Speed Search The speed search function detect the actual speed of a motor that is coasting without control and restart it smoothly from that speed. It is also activated after momentary power loss detection when L is set to enabled. Set either external search command 1 or external search command 2.
Page Speed Calculation Search at Startup The time chart for when speed search at startup and speed search to multi-function input terminals is shown below. Deceleration time set in b Set frequency refer- Run command ence Starts using calculated speed Output frequency b Output current 0.
Page Current Detection Speed Search at Startup The time chart when speed search at startup or external speed search command is selected is shown below. Deceleration time set in b Run command Set frequency ref- Maximum output erence frequency or set frequency Output frequency b Output current In case of very low current values as with special motors the detected speed can differ from the actual speed of the motor.
If no fault is detected, the Inverter will restart automatically. This is called the auto restart function. Set the number of allowed auto restarts in parameter L The auto restart function can be applied to the following faults. This function can be used for times when a motor should not be stopped quickly with an emergency stop. Page Inverter Protection Inverter Protection Overheating Protection for an Inverter-Mounted Braking Resistor This function provides overheat protection for inverter-mounted braking resistors Model: ERFWJ When overheating of a mounted braking resistor is detected, an fault RH mounted braking resistor overheat- ing is displayed on the Digital Operator, and the motor coasts to stop.
The fault can be output using one of the multi-function digital outputs as well. Page Inverter Overheat Protection Inverter Overheat Protection This function provides overheat protection for inverter-mounted braking resistors Model: ERFWJ When overheating of a mounted braking resistor is detected, an fault RH mounted braking resistor overheat- ing is displayed on the Digital Operator, and the motor coasts to stop.
This is the factory setting. Local: The digital operator is used as frequency reference and run command source. In this case the value from the input A1 becomes the fre- quency reference lower limit. If using a combination of the frequency reference from terminal A1 and the frequency reference lower limit set in either parameter d or d, the larger limit value will become the frequency reference lower limit.
Otherwise operation fault OPE03 invalid multi-function input selection will occur. Page Output Terminal Functions Output Terminal Functions The digital multifunction outputs can be set for several functions using the H to H parameters termi- nal M1 to M6 function selection. These functions are described in the following section.
Page Inverter Operation Ready Setting: 6 If a multifunction output is programmed for this function the output will be switched ON when the initialisa- tion of the inverter at startup has finished without any faults. Page Motor 2 Selection Setting: 1C If a multifunction output is programmed for this function the output is switched ON when motor 2 is selected. During Regenerative Operation Setting: 1D If a multifunction output is programmed for this function the output is switched ON when the motor works regenerative, i.
Page Using The Pulse Train Monitor Output Adjustment Examples The influence of the settings of gain and bias on the analog output channel is shown on three examples in 6. Page Application Precautions When using the pulse monitor output, connect a peripheral device according to the following load conditions.
If the load conditions are different, there is a risk of characteristic insufficiency or damage to the inverter. Serial com- munications between master and slave are normally started by the master and the slaves respond. Page Function Code The function code specifies commands. The three function codes shown in the table below are available. Bytes Max. Bytes Min. Bytes Read memory register contents Loop back test Write multiple memory registers Data Configure consecutive data by combining the memory register address test code for a loop back address and Page The following example clarifies the calculation method.
It shows the calculation of a CRC code with the slave address 02H and the function code 03H The example calculation in this example is not done completely normally data would follow the function code. Reading Inverter Memory Register Contents The content of maximum 16 inverter memory registers can be readout at a time. Among other things the command message must contain the start address of the first register that is to be read out and the quantity of registers that should be read out.
Page Writing to Multiple Inverter Memory Registers The writing of inverter memory registers works similar to the reading process, i. The to be written data must be consecutive, starting from the specified address in the command message. Page Data Tables The data tables are shown below. The types of data are as follows: Reference data, monitor data, and broadcast data.
Reference Data The reference data table is shown below. These data can be read and written. They cannot be used for monitor- ing functions. Monitor data can only be read. Register Address. Page Register Address. Page Inverter Fault Codes Broadcast Data Using broadcast data a command can be given to all slaves at the same time. The slave address in the com- mand message must be set to 00H. All slaves will receive the message.
They will not respond. The following table shows the broadcast data. When a communications fault overrun, framing, parity, or CRC is detected in the command message. By setting the delay time, you can prevent chattering of the sensors and switches. Set one of the parameters H to H digital input terminal S3 to S7 to 18 timer function input. By com- bining proportional control P , integral control I , and differential control D , you can even control system with load fluctuation.
The characteristics of the PID control operations are given below. Response Before adjustment After adjustment Time Set a Rapidly Stabilizing Control Condition To rapidly stabilize the control even if overshoot occurs, reduce integral time I , and lengthen differential time D. When the load varies rapidly, the Inverter response is delayed, and the machine might get be damaged or the motor may stall.
In this case, reduce the set value to speed up Inverter response. Otherwise if the PID feedback gets lost, the Inverter output frequency may accelerate to the maximum output frequency. The inverter operation will resume, if the PID output value exceeds the sleep operation level for the time set in parameter b or longer. The PID target value becomes the frequency reference value. Energy-saving control can be performed in all control methods.
The parameters to be adjusted are different for each. Page Field Forcing Field Forcing The field forcing function controls the motor flux and compensates the flux establishment delay of the motor. Thereby it improves the motor responsiveness on changes in the speed reference or the load. Field forcing is applied during all operation conditions except DC Injection.
Using parameter d a field forcing limit can be applied. Motor Rated Slip Setting E Set E to the motor rated slip calculated from the number of rated rotations on the motor nameplate. It is not rec- ommended to change the settings when the motor is used in Open Loop or Closed Loop vector control mode.
The factory setting for E is F. Page 0. For a V class motor, multiply all voltages by 2. Page 2. Output voltage V Frequency Hz Fig 6. In the Vector Control modes the motor data are set automatically by autotuning. If the autotuning does not complete normally, set them manually refer to page , Manual Setting of the Motor Parameters. It is not recommended to change the settings when the motor is used in open loop vector mode.
Page Torque Control Torque Control With Closed Loop Vector control the motor's output torque can be controlled by a torque reference from an analog input. Torque control can be enabled by setting parameter d to 1 or 2.
Page Torque Control Operation Torque Control Operation In torque control a torque value can be given as reference for the motor output. If the torque command and the load are not balanced, the motor accelerates or decelerates. The speed limit circuit prevents the motor speed from rising above certain value set by an analog input or parameter d Page The direction of the torque output from the motor will be determined by the sign of the analog signal input or a digital input command. It does not depend on the direction of the run command.
This differs from the operation of the speed limit setting. To use the speed limit bias, set d to 0 and set the bias in d as a percentage of the maximum output frequency. Page put by the speed limiter is the same as the actual load, the motor will stop accelerating and run at a constant speed. Page Droop Control Function Droop Control Function Droop control is a function that allows to achieve a load sharing between two motors that drive a single load.
The Droop Control function must be enabled at one inverter only. If by this inverter the torque rises, the speed is reduced and the other inverter takes over more load. This means, that if the frequency reference falls below the Zero-Speed level parameter b a position loop is activated and the motor is kept at the position, even if a load is applied.
Page Timing Chart An example timing chart for the Zero-Servo function showing the input and output signals is given in the fig- ure below. Page Kinetic Energy Buffering The function can be activated using a multifunction input i. A wiring example is shown in Fig. To set up this parameter do the following: Increase C until a UV1 fault is detected during deceleration.
Page Speed Follower Function Speed Follower Function The speed follower function allows a slave drive to precisely follow the speed of a master encoder or drive. The speed ratio between the master and the follower is infinitely adjustable. In addtion, a gear ratio adjustment can be added to the speed reference via parameter, analogue input, multi-funtion digital input MOP or serial communication.
