The slip compensation function compensates for the motor slip to match the actual motor
speed to the reference frequency
Slip compensation automatically adjusts the output frequency based on the motor load to
improve the speed accuracy of the motor mainly in V/F mode.
Slip compensation adjustment in V/F mode
Slip compensation gain at low speed (18-00)
The default setting of 18-00 is
“
0.0
”
, when 18-00=0, the slip compensation function is disabled.
The adjustment of slip compensation gain at low speed follows the below procedure:
(1)
Set the rated slip and the motor no-load current (02-00)
(2)
Set the slip compensation (18-00) to1.0 (factory default setting is 0.0 in V / F control mode)
(3)
For the operation with a load attached, measure the speed and adjust the slip gain (18-00)
accordingly (increase in steps of 0.1)
If the motor speed is lower than frequency reference, increase the value of 18-00
If the motor speed is higher than frequency reference, decrease the value of 18-00
When the output current(12-18) is greater than the no-load current(02-00, the slip
compensation is enabled and then output frequency increase from f1 to f2. Refer to figure
4.3.99, the slip compensation value is calculated as follows:
