Servo Motor Following Error During Sequence 9
Description:
The Servo Motor Following Error! During Sequence Number [9] alarm occurs after the new bar has been
measured and is being advanced to top-cut position. The torque on the servo motor will build up when an
obstacle prohibits the stock from moving, once the torque reaches a certain limit the PLC instructs the
servo amplifier to quit pushing and this alarm message appears on the remote control station.
Solution:
Alarm needs to be cleared. Press the STOP key on the remote control station to clear the message and
reset the alarm.
Check that nothing can prevent the bar stock from moving forward.
Check that the correct bar stock diameter is entered for the parameter.
Cause Solution
