Factory setting: 0.100
Settings 0.001~10.000sec
The slip compensation response time can be set by Pr.01-21 and Pr.01-22 and maximum up to 10 sec.
When Pr.01-21 and Pr.01-22 are set to 10 sec, it is the slowest response time the drive supports. If the
response time is set too quick, the system may be unstable.

This parameter sets the amount of additional voltage output during operation to get greater torque.

Factory setting: 0.00
Settings
0.00～10.00
When AC motor drive drives the induction motor, slips increase as load increase. This parameter can be
used to set compensation frequency and reduce the slip to close the synchronous speed when the motor
runs in the rated current to raise the drive accuracy. When drive’s output current is greater than the motor
current at no-load, the drive will compensate the frequency according to the setting in this parameter.
When actual speed is slower than expected, increase the value in Pr.01-24; if actual speed is faster than
expected, lower the value in Pr.01-24.
This parameter is valid for SVC mode only.
