 Stopping Due to Motion Control Period Exceeded Error
If motion control processing does not end within two periods, a Motion Control Period Exceeded
error occurs. All axes stop immediately.
Precautions for Correct UsePrecautions for Correct Use
When you use an NX701 CPU Unit and operate in the multi-motion, all axes in both tasks will
stop immediately if a Motion Control Period Exceeded error occurs in either of the tasks.
Refer to A-6-2 Motion Control for multi-motion.
 Errors That Cause the Servo to Turn OFF
An immediate stop is performed if an error occurs that causes the Servo to turn OFF. When the
Servo is turned OFF, the Servo Drive will operate according to the settings in the Servo Drive.
 Stopping Due to Start of MC Test Run
All axes will decelerate to a stop at their maximum deceleration if a MC Test Run is started from the
Sysmac Studio.
 Stopping Due to End of MC Test Run
All axes will decelerate to a stop at their maximum deceleration if a MC Test Run is stopped from the
Sysmac Studio.
• Click the Stop MC Test Run Button on the MC Test Run Tab Page of the Sysmac Studio.
• Close the MC Test Run Tab Page on the Sysmac Studio.
• Exit the Sysmac Studio.
 Stopping Due to Change in CPU Unit Operating Mode
All axes will decelerate to a stop at their maximum deceleration if the CPU Unit operating mode
changes.
Precautions for Correct UsePrecautions for Correct Use
• If an error that results in deceleration to a stop occurs during execution of a synchronous
movement instruction that has a Deceleration input variable, the axis decelerates to a stop at
the deceleration rate given by Deceleration.
• If an error that results in deceleration to a stop occurs 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
• When RUN mode changes to PROGRAM mode, any motion control instructions for current
motions are aborted. The CommandAborted output variable from the instructions remains
FALSE. The Servo remains ON even after changing to PROGRAM mode.
• If the operating mode returns to RUN mode while a deceleration stop is in progress after the
operating mode changes from RUN to PROGRAM mode, the output variables from motion
control instructions are cleared. The CommandAborted output variables from the motion con-
trol instructions therefore remain FALSE.
• The save process will continue during a save for the MC_SaveCamTable Instruction.
• The generation process will continue when generation of the cam table is in progress for the
MC_GenerateCamTable (Generate Cam Table) instruction.
