Stop

This section describes how to stop control.
Each control is stopped in the following cases.
Axis operation stop
• When each control is completed normally
• When the "forced stop input" is turned OFF
• When the drive unit power supply is turned OFF
• When the drive unit network disconnection is detected
• When the drive unit error occurs
• When the forced stop is input to the drive unit
• When "Enable" of MC_Power is FALSE
• When "ServoON" of MC_Power is FALSE
• When the hardware stroke limit upper/lower limit error occurs
• When a CPU module error occurs
• When the "PLC READY [Y0]" is turned OFF
• When the software stroke limit upper/lower limit error occurs
• When an axis error is detected
• When "Execute" of MC_Stop is TRUE
• When the "Stop signal" of external input signal is TRUE
Hardware stroke limit upper/lower limit error
• Error "FLS Signal Detection (at Start)" (error code: 1A2DH)
• Error "RLS Signal Detection (at Start)" (error code: 1A2EH)
• Error "FLS Signal Detection (Controlling)" (error code: 1A2FH)
• Error "RLS Signal Detection (Controlling)" (error code: 1A30H)
Axes group operation stop
• When each control is completed normally
• When a stop cause occurs in the configuration axis
• When an axes group error is detected
• When "Execute" of MC_GroupStop is TRUE
• When the "Stop signal" of external input signal is TRUE
This section describes stop processing other than when each control in the above cases is completed normally.
For operation details when a stop cause occurs in another function (stop processing of homing, etc.), refer to each function.

Details
Selects operation when the hardware stroke limit upper/lower limit error
occurs.
1: ImmediateStop (Immediate Stop) (Initial value)
2: KeepCurrentAcc (Keep current acceleration/deceleration)
3: AlternativeAcc (Alternative acceleration/deceleration)
(Immediate stop will be executed when executing an instruction without
deceleration specification.)
