Run Command
Output Frequency
C2-01
V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Sets the gain for the motor slip compensation function used for motor 1.
V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Adjusts the slip compensation function delay time used for motor 1.
V/f V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/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 V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
0: Disabled.
1: Enabled above 6 Hz.
2: Enabled whenever slip compensation is possible.
V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/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-Ao2A0004 to 2A0415, 4A0002 to 4A0675, and
5A0003 to 5A0242: Available when A1-02 = 0,1.
CIMR-Ao4A0930 and 4A1200: Available when A1-02 = 2, 3.
A1000 HHP: Available when A1-02 = 2, 3.
V/f V/f w PG OLV OLV
OLV/PM AOLV/PM CLV/PM
Sets the output voltage limit operation start level (percentage modulation)
when C3-05 is enabled.
Note: This parameter is only available in models CIMR-Ao4A0930,
4A1200, and A1000 HHP.
