V/f V/f w/PG
OLV/PM AOLV/PM
Sets the gain used for Energy Saving.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets a time constant for Energy Saving.
V/f V/f w/PG
OLV/PM AOLV/PM
Determines the level of maximum motor efficiency. Setting range is 0.0 to 2000.0 maximum
output up to 3.7 kW. The display resolution depends on the rated output power of the drive after
the Drive Duty has been set in parameter C6-01. Refer to
Check on page 32.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets a time constant filter for output power detection.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets the limit for the voltage search operation as a percentage of the motor rated voltage.
V/f V/f w/PG
OLV/PM AOLV/PM
Coefficient to adjust torque linearity
Set to the Kt value on the motor nameplate.
When E5-01 (Motor Code Selection (for PM Motors)) is set to 1 or 2, the
automatically calculated value will be set. This set value cannot be changed.
V/f V/f w/PG
OLV/PM AOLV/PM
Coefficient to adjust torque linearity
Set to the Kt value on the motor nameplate.
When E5-01 (Motor Code Selection (for PM Motors)) is set to 1 or 2, the
automatically calculated value will be set. This set value cannot be changed.
V/f V/f w/PG
OLV/PM AOLV/PM
Sets a compensation method for the q-Axis current when output voltage is limited.
There is normally no need to change this parameter from the default value.
0: Output Voltage Limit Priority
1: q-Axis Current Priority
Note: This parameter is not available in models CIMR-A4A0930 and 4A1200.
