FIELD CURRENT TRACKING FAULT

¿Qué significa 413 ?

The actual field current is failing to track the field current command by more than F192 (default = 0.05PU) for 5 seconds. This is not a shutdown fault, but a warning.

• Incorrect AC voltage on AC1 and AC2.
• Drives not using correct self-tune values.
• Field response set incorrectly.
• Failing to track field current command by more than F192 for 5 seconds.

1. 1

   Check AC voltage on AC1 and AC2; it should typically be 1.5 to 2.5 times VACmin where VACmin = VDC/0.9 or (Full Fld Amps * Field resistance)/0.9.

2. 2

   Verify that the drive is using correct self-tune values and/or field response settings.

3. 3

   Monitor F620 (Fld Trkg Diff); it should be less than F192.

4. 4

   Adjust F192 ('F413 Detect Level') to a higher value if necessary, but observe caution prior to doing this.
