Setting the forced stop
To use the "Forced stop function", set the following data using a program.
"[Pr.82] Forced stop valid/invalid selection" is validated at the rising edge (OFF  ON) of the PLC READY signal [Y0] and
"[Cd.158] Forced stop input" checks in the operation cycle.
"[Cd.158] Forced stop input" is validated only when "[Pr.82] Forced stop valid/invalid selection" is set to "2: Valid (Buffer
memory)".

Precautions during control
• After the "Forced stop input" is released, the servo ON/OFF is valid for the status of all axis servo ON [Y1].
• If the setting value of "[Pr.82] Forced stop valid/invalid selection" is outside the range, the error "Forced stop valid/invalid
setting error" (error code: 1DC1H) occurs.
• "[Md.50] Forced stop input" is stored "1" by setting "[Pr.82] Forced stop valid/invalid selection" to "1: invalid".
• When the "Forced stop input" is turned ON during operation, the error "Servo READY signal OFF during operation" (error
code: 1A02H) does not occur.
• The status of the signal that is not selected in "[Pr.82] Forced stop valid/invalid selection" is ignored.
• Errors cannot be cleared by "[Cd.5] Axis error reset" during forced stop. Clear errors after forced stop is released.
• If "[Cd.158] Forced stop input" is set to "0000H: Forced stop ON (Forced stop)" during the operation with "[Pr.140] Driver
command discard detection setting" set to "1: Detection enabled", an error "Driver command discard detection" (error code:
1BE6H) may occur before turning the servo OFF.
