4.2.3 Adjusting Synchronized Stopping
Set Pn668 (Synchronized Stopping Speed Feedforward) to apply feedforward compensation
which can reduce the deviation between the feedback position of the active alarm axis and the
position of the synchronized stopping axis. This parameter is valid for synchronized stopping
mode 1.
For details on the setting of this parameter, contact your Yaskawa representative.
Note: During model following control, select Pn140 = n.1 (Use model following control and speed/torque
feedforward together). This parameter is not valid if Pn140 = n.0 (Do not use model following control
and speed/torque feedforward together) is selected.
