1 OUTLINE OF ADVANCED SYNCHRONOUS CONTROL
1.3 Operation Method of Synchronous Control
Stop operation of output axis
If the following causes occur in stopping the output axis during synchronous control, synchronous control is completed after
stops processing for the output axis (BUSY signal is OFF, axis operation status is standby).
Synchronous alignment must be executed for the output axis to restart the synchronous control (Page 122 Output Axis
Module).
*1 Refer to "Stop" in the following manual for details.
MELSEC iQ-R Motion Module User's Manual (Application for Simple Motion Mode)
Immediate stop
The operation stops without deceleration. The Motion module immediately stops the command, however, the operation will
coast for the droop pulses accumulated in the deviation counter of the servo amplifier.
