Hva betyr OL1 ?

This fault indicates that the Altivar 212 drive is overloaded, often due to excessively short acceleration times, high DC injection current, incorrect motor control settings, or a rotating load.

• Acceleration time is too short (ACC or F500).
• DC injection current level (F251) is too high.
• Incorrect setting of [Mot cont. mode sel.] (Pt).
• Drive is starting into a rotating load.
• Excessive mechanical load is applied to the motor.
