Stop cause
Forced stop "Forced stop input signal" OFF
from an external device
Servo READY OFF
• Servo amplifier power supply
OFF
• Servo alarm
• Forced stop input to servo
amplifier
Fatal stop Hardware stroke limit upper/lower
(Stop group 1) limit error occurrence
Emergency stop Error occurs in a CPU module
(Stop group 2)
PLC READY signal OFF
Relatively safe Axis error detection (Error other
stop than stop group 1 or 2)
(Stop group 3)
Intentional stop "Axis stop signal" ON from a CPU
(Stop group 3) module
*1 If an error occurs in a positioning data due to an invalid setting value, when the continuous positioning control uses multiple positioning
data successively, it automatically decelerates at the previous positioning data. It does not stop rapidly even the setting value is rapid
stop in stop group 3. If any of the following error occurs, the operation is performed up to the positioning data immediately before the
positioning data where an error occurred, and then stops immediately.
No command speed (error code: 1A12H)
Outside linear movement amount range (error code: 1A15H)
Large arc error deviation (error code: 1A17H)
Software stroke limit + (error code: 1A18H)
Software stroke limit - (error code: 1A1AH)
Sub point setting error (error code: 1A27H)
End point setting error (error code: 1A2BH)
Center point setting error (error code: 1A2DH)
Outside radius range (error code: 1A32H)
Illegal setting of ABS direction in unit of degree (error code: 19A4H)
Provide the emergency stop circuits outside the servo system to prevent cases where danger may result from
abnormal operation of the overall system in the event of an external power supply fault or servo system
failure.
