Dear friend,
I repairing Lathe machine MORI SEIKI CL20A MCS 518, use Fanuc 18 TB controller.
Now machine issuse EX 377 Error : TURRET COUNTER A IS ABNORMAL.
Anybody help me to solve this problem, i have not electrical manual,
The machine set password for PMC program so i can not access.
If you have this password please show me to solve this problem.
Thanks in advance.

BKCOM,
I dont know the password, but if you send the ladder program to me, its posible i broke the password.

P.S. This alarm, maybe, inside the turret has 2 sensors. One that count in CW direction and another one in CCW direction. Maybe one this sensors are broken
you may want to check the proximity switch SQ-9 for turret count A (Input Signal X1004.0) and proximity switch SQ-8 for turret count B (Input Signal X1004.1). Both switches situated at rear of turret face.
Mori ladder password is usually "L".
EX alarms are ladder generated, therefore machine sensor, therefore probably a faulty prox inside turret.
You can check prox status in DIAG screen. Just use the electrical drawings to find the right input.
