4.2 Parameter Settings Related to Synchronized Stopping
4.2.1 Synchronized Stopping Mode Selection
Synchronized Stopping has three modes, and these modes are set with Pn665 = n.  X
(Synchronized Stopping Selection).
Synchronized Stopping Mode 1
If an alarm occurs on either axis A or axis B, position control will be performed on the synchro-
nized stopping axis using the feedback position of the active alarm axis as the target position.
Synchronized Stopping Mode 2
If an alarm occurs on either axis A or axis B, speed control will be performed on the synchro-
nized stopping axis using the feedback speed of the active alarm axis as the target speed.
Synchronized Stopping Mode 3
If an alarm occurs on either axis A or axis B, the synchronized stopping axis is also set to the
servo OFF state.
Both axes are changed to the servo OFF state almost simultaneously, and both axes are
stopped according to the Servomotor stopping method when the servo is turned OFF.
4.2.2 Synchronized Stopping End Speed Setting
Synchronized stopping will be ended when the feedback speed of the active alarm axis is less
than Pn666 (Synchronized Stopping End Speed).
Use Pn666 (Synchronized Stopping End Speed) to set the speed for judging that the Servomo-
tor has stopped and ending synchronized stopping. This parameter is valid for synchronized
stopping mode 1 and 2.

With synchronized stopping mode 1 and 2, the Servomotor may vibrate and the deviation
between axes may increase when synchronized stopping is performed due to the mechanical
characteristics or gain setting.
Use this function by first operating the machine or product at low speed and confirming that the
deviation between axes causes no problems.
