Feedforward
The feedforward gain (Pn109), speed feedforward input, and torque feedforward input will be disabled in the
factory setting.
Set Pn140.3 to 1 if model following control is used together with the speed feedforward input and torque feed-
forward input from the host controller (through the command option module).
Pn140
For details on the speed feedforward input and the torque feedforward input, refer the the manual of the con-
nected command option mocule.

Parameter
n.0
Model following control is not used together with the
speed/torque feedforward input.
[Factory setting]
Model following control is used together with the
n.1
speed/torque feedforward input.
• Model following control is used to make optimum feedforward settings in the SERVO-
PACK when model following control is used with the feedforward function. Therefore,
model following control is not normally used together with either the speed feedfor-
ward input or torque feedforward input from the host controller. However, model fol-
lowing control can be used with the speed feedforward input or torque feedforward
input if required. An improper feedforward input may result in overshooting.
