C3-01 Slip com-
pensation
gain. Used to improve speed
accuracy when operating with a
load.
Note: Usually setting is not nec-
essary.
When actual speed is low,
increase the set value.
When actual speed is
0.0 to
2.5 1.0
(See
note.) OK B X B B 6-59,

Slip Comp
Gain
When actual s eed is
high, decrease the set
value.
In flux vector control
mode this function be-
comes gain to compen-
sate for slip caused by
temperature variation.
C3-02
Slip com-
pensation
primary
delay time.
Slip compensation primary
delay time is set in ms units.
Note: Usually setting is not nec-
essary.
Adjust when slip com-
pensation responsiveness
is low, or speed is not sta-
bilized.

C3-05 Flux Cal-
culation
Method Used to set the flux calculation
method. Normally, this setting is
not required.
0:
Flux is calculated based on
the output frequency after
frequencies using slip
compensation, etc.
1: Flux is calculated based on
the output frequency before
0, 1 0 NO X X A X 6-6
Flux Select
the output frequency before
correcting frequencies using
slip compensation, etc.
Note: Set to “1” when motor
rotation becomes unsta-
ble due to interference
using slip compensation.
