Run Command
Output Frequency
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the gain for the motor slip compensation function used for motor 1.
V/f V/f w/PG
OLV/PM AOLV/PM

V/f V/f w/PG
OLV/PM AOLV/PM
Sets an upper limit for the slip compensation function as a percentage of motor rated slip for
motor 1 (E2-02).
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled.
1: Enabled above 6 Hz.
2: Enabled whenever slip compensation is possible.
V/f V/f w/PG
OLV/PM AOLV/PM
0: Disabled.
1: Enabled. Automatically decreases motor flux when output voltage saturation is reached.
Note: Available control mode for parameter C3-05 varies by drive model:
CIMR-A2A0004 to 2A0415 and 4A0002 to 4A0675: Available when A1-02 = 2, 3
