When inverter executes auto tuning function, Fmax value sets by 02-06
When inverter does not execute auto tuning function, Fmax value sets by 01-02

Auto tune function in SLV mode. 00-00=【1】
Set motor parameters 02-01 and 02-03~02-06，then set 02-07=1 to start the auto tune
function.
During the Auto tune function the display will show AT and show END briefly when auto tune is
completed then the display will return to the frequency display.
Following an auto tune the motor test data are stored in parameters 02-08&02-09
then the setting in 02-07 will automatically reset to 0.
Notes:
Carry out Auto tune again whenever replacing the motor.
Auto tune function is not possible for applications with multi-motor connected to one inverter.
Auto tune can be used on motors of equivalent size to the inverter or one size smaller(or one
size bigger). Just need to set the motor parameter and set 02-07 to be 1.
Parameters 02-00 ~ 02-06 are available both for V/F & SLV mode (Except parameter 02-02
which is for V/F).
02- 13 SLV Slip Compensation Gain
Range 【0~200】%
02- 14 SLV Torque Compensation Gain
Range 【0~200】%
SLV Slip compensation
When the load causes the actual motor speed to be reduced below the speed set by
inverter output frequency (Slip), parameter 02-13 SLV Slip compensation can be used to
correct the speed.
SLV Torque compensation:
When torque is reduced due to load conditions, parameter 02-14 can be used to correct the
torque. Torque producing current adjusted to compensate for the reduced torque.
02-13、02-14 compensation is based on the load current. The unit of 02-13 is based on rated
slip frequency; The unit of 02-14 is based on rated torque difference.
The adjustment for 01-14 can be increased or decreased every time about 5% to 10%.
02- 15 Low Frequency Torque Gain
Range 【0~100】%
Inverter of dead zone (IGBT on short) will lower the torque of output in the system, leading
to lower motor efficiency. Setting 02-15 can not only reduce this situation but also increase
torque of output in low frequency. Default setting is 50, means 50% voltage compensation.
100% of 02-15 according to output voltage that is less affected by dead zone.
02- 16 SLV Without Load Slip Compensation Gain
Range 【0~200】%
