Sets the gain for the motor slip compensation function used for
motor 1.
Adjusts the slip compensation function delay time used for
motor 1.
Slip Comp Time
Sets an upper limit for the slip compensation function as a
percentage of motor rated slip for motor 1 (E2-02).
0: Disabled.
Slip Comp Regen 1: Enabled above 6 Hz.
2: Enabled whenever slip compensation is possible.
0: Disabled.
1: Enabled. Automatically decreases motor flux when output
voltage saturation is reached.
Note:
Output V Lim Sel
Sets the output voltage limit operation start level (percentage
modulation) when C3-05 is enabled.
Output V Lim Sta
Note:
Sets the output voltage limit operation determined by C3-18
(percentage modulation) when C3-05 is enabled.
Output V Lim Max
Note:
Sets the maximum percentage of output voltage reduction
when C3-05 is enabled.
Output V Lim lev
Note:
Sets the slip compensation gain used for motor 2.
