Slip compen- Used to improve speed accu-
sation gain racy when operating with a
load.
Usually setting is not neces-
sary.
Adjust this constant at the fol-
lowing times.
C3-01
• When actual speed is low,
滑差补偿增益
increase the set value.
• When actual speed is high,
decrease the set value.
Used as the applicable control
gain when using flux vector
control.
Slip compen- Slip compensation primary
sation pri- delay time is set in ms units.
mary delay Usually setting is not neces-
