Machine Control System Stop Operation

When one of the following stop causes occurs in a machine configuration axis during machine control, after the stop
processing of all machine configuration axes, "[St.2127] Machine start accept flag (M43911+32m)" turns OFF, and machine
control ends.
Stop cause
Multiple CPU system reset operation
Multiple CPU system power supply OFF
Motion CPU WDT error
Forced stop (forced stop by Motion controller (device)
Forced stop (servo amplifier forced stop input terminal)
Servo error occurrence
Servo amplifier control circuit power supply turns OFF
Software stroke limit error occurrence for each axis
XYZ stroke limit error occurrence
Input from external input signals (STOP/FLS/RLS) (Stop processing at STOP input: Deceleration stop)
Motion CPU RUNSTOP
Stop command input
Machine stop command input
Servo motor maximum speed check
Input from external input signals (STOP/FLS/RLS) (Stop processing at STOP input: Rapid stop)
Rapid stop command input
Machine rapid stop command input
Refer to the following for details of stop processing.

Machine Control System Device Assignment
Method
"MELSEC iQ-R Motion device assignment" is the recommended device assignment method when using machine control.
Refer to the following for details of device assignment methods.
MELSEC iQ-R Motion Controller Programming Manual (Common)
Refer to machine control dedicated signals for devices used by machine control.(Page 25 MACHINE CONTROL
DEDICATED SIGNALS)
Cautions
When performing machine control with R32MTCPU/R16MTCPU in "Q series Motion compatible device assignment", set the
points of the internal relay(M) and data register(D) to the points below or more in [R Series Common Parameter]  [Motion
CPU Module]  [CPU Parameter]  "Device Related Setting"  "Device Points/Latch Setting". If machine control is
performed with the default device points a moderate error (error code: 30FBH) occurs and machine control cannot be
performed.
Device
Internal relay (M)
Data register (D)
Refer to the following for details on device points/latch setting.
