SLV With Load Slip Compensation Gain
Range
【0~200】%
 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）]

SLV Slip Compensation Select
Range
0: Slip Compensation Select 1
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.
