4-30
 Set motor parameters 02-01 and 02-03～02-06，next set 02-07 to【1】to start the auto tune procedure.
 During the Auto tune the display will show AT and show END briefly when auto tune is completed then the
display will return back to show frequency.
 After a successful auto tune the motor test data is stored in parameters 02-08 and 02-09 and parameter 02-07 is
set back to 0.
Notes:
 Perform an auto tune whenever the motor is replaced.
 Auto tuning is not possible for applications with multiple motors connected to one inverter.
 Auto tune can be used on motors of similar size to the inverter or one size smaller. Make sure to set the correct
motor parameters.
 Parameters 02-00 ~ 02-06 are available both for V/F & SLV mode (Except parameter 02-02 V/f only).
02-13
SLV Slip Compensation Gain
Range
【0~150】%
02-14
SLV Torque Compensation Gain
Range
【0~100】%
SLV Slip compensation
 When the load causes the actual motor speed to fall below the set speed due to the slip of the motor,
parameter 02-13 (SLV only) can be used to compensate and correct the speed.
SLV Torque compensation
 When torque is reduced due to load conditions, parameter 02-14 can be used to correct the torque producing
current and compensate for the reduced torque.
 Both 02-13 and 02-14 compensation are based on the load current. Parameter 02-13 is based on rated slip
frequency and 02-14 is based on the difference in rated torque.
 Adjust 02-14 in steps of 5 to 10% up or down if needed.
02-15
Low Frequency Torque Gain
Range
【0~100】%
 When operating at low output frequency (IGBT dead zone) results in a lower output torque of the
system and therefor resulting in lower motor efficiency. Setting 02-15 can increase output torque at low
frequency. Default setting is 50% voltage compensation. 100% of 02-15 is based on the output voltage of
the dead zone.
