●Current Value Warnings
After the end of the fastening operation, it is judged whether or not the peak current value
during operation is within the high and low limit ranges. If the peak current value during
operation falls below the low current limit or exceeds the high current limit, although the Unit
outputs the ACCEPT Spindle judgment, the PLC layout output signal “Multi: Current Limit
Warning,” “Spindle: Current Limit Warning,” “Spindle: Current Low Warning,” or “Spindle:
Current High Warning” is turned “ON.”
・The current value warning judgment cannot be made unavailable.
・As the full scale current, a value based on the motor used is set automatically in accordance
with the model of the Unit. Do not change this value if there is no special reason to do so.
· Converted value of current 100% differs depending on the motor type of the tool used.
(M50 : 10 A, M 80 : 16 A, M 120 : 21 A)
Also, the current limit value limits the maximum value of the current during the fastening
operation. The current limit value is used to protect the motor during the execution of the torque
recovery, which is an after-fastening operation. When the current limit is exceeded, the fastening
is stopped and the abnormal state signal A05-01 “Servo Reply Error” is generated.
520: No Load Current Limit:10%
523: Fastening Current Limit :100%
522: High Current Warning :100%
521: Low Current Warning : 0%
