Saturation Trip

What does 7 mean?

This fault signifies a critical issue such as a defective internal component or a short-circuit/overload condition in the brake resistor. This fault cannot be reset from the keypad, requiring a power cycle of the drive. If occurring with Fault 1, it suggests a motor cable or motor issue.

• Motor exceeds rated torque, causing current to reach saturation limits.
• Overload condition due to excessive mechanical load on the driven equipment.
• Incorrect motor sizing for the application, leading to continuous high current draw.
• Faulty motor winding or insulation failure causing increased current.
• Parameter P1-12 (Maximum Current Limit) set too low for operational demands.

Click steps to track your progress.

1. 1

   Switch off all power to the AC drive at the main circuit breaker.

2. 2

   DO NOT RE-CONNECT POWER until further investigation.

3. 3

   If this fault occurred simultaneously with Fault 1 (Overcurrent), thoroughly inspect the motor cables and the motor for any damage or short circuits.
