Overcurrent During Acceleration

Hva betyr OC1 ?

This fault indicates an overcurrent condition during motor acceleration by the Altivar 212 drive, often caused by excessively short acceleration times, incorrect motor control settings, or high-inertia loads.

• Acceleration time is too short (ACC or F500).
• Incorrect setting of [Mot cont. mode sel.] (Pt).
• Drive is starting into a rotating load.
• Drive is powering a low impedance motor.
• Ground fault in the motor or cables.
