NEED HELP!
Okuma LNC-8 OSP5020L Control
Alarm 100-4 DIF over Z axis 5D26
only occurs during peck drilling cycle, Z axis load only reaches 105% instantaneously shuts down.
Have removed all the way covers to verify that ways are clear, cleaned, and well oiled. In the last year we have replaced the Axis Servo drives. Machine has been running fine. Only shows a problem during pecking.
What should we be looking for?
THANKS!!
