OC5
Overcurrent
Lenze · 9300 Servo Controller
What does OC5 mean?
An overcurrent condition (OC5) can be activated if motor phases are reversed, causing the motor's rotating field to mismatch the feedback system's. This leads to the motor drawing high current, potentially up to Imax (C0022), especially with V/f or vector control.
