Power turret alarms while change to the No.3 tool, no matter under Jog or MDI mode. And there is emergency alarm as well.
Normally this problem could be below reasons:
1- The feedback cable of No.3 tool is shorted.
2- The inductive sensor inside the power turret is shorted.
3- The mechanical parts of the power turret stuck, causes switch trip off and then emergency alarms.
4- Parameters of the CNC controller has mistakes.
Check step by step, we measured the resistance value of No.3 tool is different with other 3 tools, change the inductive sensor, the power turret resumed.
