Droop Control
Sets the speed decrease as a percentage of motor base speed
(E1-06) when the motor is at 100% load torque. Setting of 0.0
disables droop control.
Determines the droop control delay time in response to a load
change.
Energy Saving
Energy Savings function enable/disable selection.
0: Disabled
1: Enabled
Sets energy savings control gain when in vector control method.
Sets energy saving control filter time constant when in vector
control method.
Used to fine-tune the energy savings function when in V/F control
method.
Zero Servo
Sets the position loop gain for Zero Servo command.
This function is effective when multi-function input "zero
servo command" is set.
Sets number of pulses used for the multi-function output of
"zero servo completion".
