(Note-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 503)
• Outside linear movement amount range (Error code 504)
• Large arc error deviation (Error code 506)
• Software stroke limit + (Error code 507)
• Software stroke limit - (Error code 508)
• Sub point setting error (Error code 525)
• End point setting error (Error code 526)
• Center point setting error (Error code 527)
• Outside radius range (Error code 544)
• Illegal setting of ABS direction in unit of degree (Error code 546)
(Note-2): The failure during the test mode occurs in the following case.
• When the communication cannot be executed between the personal computer and the PLC CPU
(Note-3): The stop process when using the driver HPR method follows the specification of the servo amplifier. [CiA402 mode]
REMARK
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.
