Servo ON/OFF
Sub functions for an input axis in synchronous control conform to the specification of each control (home
position return control, positioning control, manual control, speed torque control). Refer to "CONTROL SUB
FUNCTIONS" in the following manual for details.
MELSEC iQ-R Motion Module User's Manual (Application for Simple Motion Mode)
The delay time inherent to the system of a command generation axis is 0, so that the phase compensation
function does not exist.
