 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 Use Precautions 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.
Additional Information
• You must set up the Servo Drive in order to use the input signals from the Servo Drive. An
OMRON 1S-series Servo Drive with built-in EtherCAT communications or G5-series Servo
Drive with built-in EtherCAT communications has an immediate stop input and limit input
assigned in its default settings.
• Refer to A-1 Connecting the 1S-series Servo Drive for setting examples for connection to an
OMRON 1S-series Servo Drive.
• Refer to A-2 Connecting the G5-series Servo Drive for setting examples for connection to an
OMRON G5-series Servo Drive.
Stopping with Motion Control Instructions
Use the MC_Stop or MC_ImmediateStop instruction to stop single-axis operation.
 MC_Stop Instruction
You can specify the deceleration rate and jerk for single-axis control and synchronized control to
decelerate to a stop. Specify a deceleration rate of 0 to send a command that immediately stops the
Servo Drive. Other operation commands are not acknowledged while decelerating to a stop for this
instruction and while the input variable Execute is TRUE.
 MC_ImmediateStop Instruction
You can perform an immediate stop for single-axis control or synchronized control functions. You
can also execute this instruction on axes that are enabled in an axes group.
For details, refer to the MC_Stop and MC_ImmediateStop instructions in the NY-series Motion Control
Instructions Reference Manual (Cat. No. W561).
