Stop During Single Axis Operation - Mitsubishi Electric MELSEC iQ-R Series User Manual

Stop during single axis operation

This section explains each stop cause.
Stop causes of immediate stop with no condition
When the following stop causes occur, the servo OFF is executed in the drive unit and the axis stops immediately.
For how to stop the drive unit, refer to each drive unit manual.
• "Forced stop input" is turned OFF from an external device
• Drive unit power supply OFF
• Drive unit network disconnection detection
• Drive unit error
• Forced stop input to drive unit
• "Enable" of MC_Power is FALSE
The forced stop input is set in AxisName.Pr.ForcedStop_Signal. For operation details, refer to the following.

Stop causes by ServoON input of MC_Power
■Processing selection at servo OFF during operation
When ServoON of MC_Power is turned FALSE, the stop operation differs depending on the
AxisName.Pr.StopMode_ServoOff setting. The processing selection at servo OFF command during operation has the
following three functions.
• Operation continuation
0: Ignore
During operation, this function ignores the servo OFF command even though it is input and continues on-going operation. If
ServoON of MC_Power is turned FALSE when the axis status (AxisName.Md.AxisStatus) of the operation completion axis
turns "4: Standstill", servo OFF will be executed. (The axis will not stop.)
• Immediate stop servo OFF
4: ServoOffAfterImmediateStop
During operation, the command is immediately stopped by the error "Immediate Stop by Servo OFF During Operation" (error
code: 1A3CH) occurrence, and a servo OFF is issued to the driver.
• Deceleration stop, and servo OFF after stop completion
5: ServoOffAfterDecelStop
During operation, when receiving the servo OFF command input, the error "Deceleration Stop by Servo OFF During
Operation" (error code: 1A3BH) occurs and deceleration stop is executed. If ServoON of MC_Power is FALSE when the
operation has reached speed 0, servo OFF will be executed.
