Slip compensa- Slip compensation gain is set as a per-
tion gain centage of the maximum output frequency
(n014). Use the following equations to set
a value that corresponds to the motor
rated slip.
n109 =100 ×
(Synchronization speed – rated motor
speed) ÷ synchronization speed
Synchronization speed = 120f/P
P: No. of polls
f: Rated frequency
Set n014 to the motor's rated frequency.
