Slip Compensation
C3-01
Slip compensa-
tion gain
• Increase the value if slip compensation 
value is too low
• Decrease the value if slip is overcom-
pensated
C3-02
Slip compensa-
tion delay time
• Reduce the value if the slip compensa-
tion responsiveness is low. 
• When speed is not stable, increase the 
setting.
Automatic Speed Regulator (ASR)
C5-01
ASR propor-
tional (P) gain 1
Set the proportional gain 1 and the inte-
gral time 1 of the speed control loop 
(ASR) for the frequency C5-07.

V/f Pattern Settings
E1-01
Input voltage 
setting
This setting is used as a reference value 
for protection functions.
E1-04
Max. output 
frequency 
(FMAX)
To set V/f characteristics in a straight 
line, set the same values for E1-07 and 
E1-09. In this case, the setting for E1-08 
will be disregarded.
Always ensure that the four frequencies 
are set in the following manner:
E1-04 (FMAX) ≥ E1-06 (FA) > E1-07 
(FB) ≥ E1-09 (FMIN)
