Current limit (VLT overload)

What does 59 mean?

The drive has reached its internal current limit due to an overload condition, similar to 'Inverter overloaded' but possibly indicating a different internal control loop limitation. This is a protection mechanism to prevent damage to the drive's power components.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Verify parameter settings for current limits (e.g., parameter 4-15 Current Limit) and ensure they are appropriately configured for the application.

2. 4

   Ensure the drive is correctly sized for the motor and application, especially for peak and continuous current demands.
