9-1-6 Stopping
Functions to stop axis operation include immediate stop input signal and limit input signals connected
to the Servo Drive, stop functions of motion control instructions in the user program, and stopping due
to errors.
Refer to the NX-series Position Interface Units User’s Manual (Cat. No. W524) for the differences when
you use NX-series Pulse Output Units.
Axis motion is stopped for the immediate stop input signal or a limit input signal from the Servo Drive.
You can select the stop method with the Sysmac Studio.
 Immediate Stop Input
Stop processing in the MC Function Module is executed according to the state of the Servo Drive
input signals. You can select one of the following stopping methods for the MC Function Module.
• Immediate stop
• Immediate stop and error reset
• Immediate stop and Servo OFF
Precautions for Correct UsePrecautions for Correct Use
The immediate stop input for the OMRON 1S-series Servo Drive or G5-series Servo Drive also
causes an error and executes stop processes in the Servo Drive itself.
 Limit Inputs (Positive Limit Input or Negative Limit Input)
Stop processing in the MC Function Module is executed according to the state of the Servo Drive
input signals. You can select one of the following stopping methods for the MC Function Module.
• Immediate stop
• Deceleration stop
• Immediate stop and error reset
• Immediate stop and Servo OFF
Precautions for Correct UsePrecautions for Correct Use
• If a limit input signal turns ON, do not execute an instruction for axis command of the axis in
the same direction as the limit input signal.
• If a limit input signal is ON for any axis in an axes group, do not execute an instruction for an
axes group command for that axes group.
• If the signal to decelerate to a stop is input during execution of a synchronous movement
instruction that has a Deceleration input variable, the axis decelerates to a stop at the deceler-
ation rate given by Deceleration.
• If the signal to decelerate to a stop is input during execution of a synchronous movement
instruction that does not have a Deceleration input variable, the axis decelerates to a stop at
the maximum deceleration rate that is set in the axis parameters.
