PWM dead zone at low frequencies below 10Hz causes torque reduction.
02- 16 SLV Without Load Slip Compensation Gain
【0~200】%
Range
02- 17 SLV With Load Slip Compensation Gain
【0~200】%
Range

1. When output current <= 02-00 (Motor current without load)
Slip compensation gain :
= [ SLV slip compensation gain(02-13）]* [Normal Duty slip compensation gain (02-16）]

2. When output current > 02-00 (Motor current with load)
Slip compensation gain:
= [ SLV slip compensation gain(02-13）] * Slip compensation gain 1
(According to the diagram below）]
02- 18 SLV With Load Torque Compensation Gain

Please refer the contents as parameter 02-13/02-14
02- 19 SLV Slip Compensation Select
0: Slip Compensation Select 1
Range
1: Slip Compensation Select 2

When output current lower or equal to 02-00(no load), the value of slip compensation will be
equal to (02-13)*(02-16)(slip compensation select 1).

When output current higher than 02-00(with load), the value of slip compensation will be equal
to (02-13)*(02-17)(slip compensation select 2).
Note: If inverter worked at lower speed with load, please use slip compensation select 2.
