Acceleration feed forward factor
●
Function
This parameter specifies the factor used to give the second-order derivative value to a torque
command. Usually set this factor to 0.
This setting is usually required to improve the speed.

Torque command filter
●
Function
For the purpose of suppressing the self-excited oscillation with the mechanical system, this
parameter specifies the factor for the cutoff frequency of the low pass filter of a torque command.
Usually set this factor to 0.

Rotary direction
(After the setting is changed, the driver must be powered on again.)
●
Function
This parameter specifies the rotary direction of the actuator.
Note: For DC servo actuator, the rotary direction is reverse to the rotation that takes place when the
monitor is used as a standalone machine. This is because the actuator is equipped with a
HarmonicDrive
®
decelerator.
0: When a forward command pulse is input, the actuator rotates in the counterclockwise direction
relative to the actuator output shaft.
1: When a forward command pulse is input, the actuator rotates in the clockwise direction relative to
the a ctuator output shaft.
* After the setting is changed, the power must be turned on again.

Note: The default is 1. When a forward command pulse signal is input, the actuator rotates
clockwise relative to the actuator output shaft.
