Sets the gain used for Energy Saving.
Sets a time constant for Energy Saving.
Determines the level of maximum motor efficiency. Setting range is 0.0 to
2000.0 for drives 3.7 kW and smaller. The display resolution depends on the
rated output power of the drive after the Drive Duty has been set in parameter
C6-01.
Sets a time constant filter for output power detection.
Sets the limit for the voltage search operation as a percentage of the motor
rated voltage.
Coefficient to adjust torque linearity.
Set to the Ki value on the motor nameplate.
When parameter E5-01, Motor Code Selection, is set to 1ooo or 2ooo,
the automatically calculated value will be set. This set value cannot be
changed.
Coefficient to adjust torque linearity.
Set to the Kt value on the motor nameplate.
When parameter E5-01, Motor Code Selection, is set to 1ooo or 2ooo,
the automatically calculated value will be set. This set value cannot be
changed.
Description
Sets the position loop gain for the Zero Servo function.
Sets the range to trigger an output terminal set for "Zero Servo Complete"
during Zero Servo operation.
