C2-01
Description
Sets the gain for the motor slip compensation function used for motor 1.
Adjusts the slip compensation function delay time used for motor 1.
Sets an upper limit for the slip compensation function as a percentage of motor
rated slip for motor 1 (E2-02).
0: Disabled.
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.
Sets the output voltage limit operation start level (percentage modulation)
when C3-05 is enabled.
Note: This parameter is not available in models CIMR-Ao4A0930 and
4A1200.
Sets the output voltage limit operation determined by C3-18 (percentage
modulation) when C3-05 is enabled.
Note: This parameter is not available in models CIMR-Ao4A0930 and
4A1200.
Sets the maximum percentage of output voltage reduction when C3-05 is
enabled.
Note: This parameter is not available in models CIMR-Ao4A0930 and
4A1200.
Sets the slip compensation gain used for motor 2.
Sets the slip compensation delay time used for motor 2.
Sets the upper limit for the slip compensation function for motor 2. Set as a
percentage of the motor rated slip (E4-02).
