I3 Incompat PS

What does 10332 mean?

The drive has detected an incompatible power supply for the drive AC input rating on port 3. This can lead to improper operation or damage if not addressed.

• Input voltage applied to Port 3 is outside the specified nominal voltage range (e.g., 690V supply connected to a 400V rated input).
• Mismatch in the number of input phases (e.g., attempting to connect a single-phase supply to a three-phase Port 3 configured drive).
• The frequency of the incoming AC power at Port 3 is outside the acceptable operating window (e.g., 50Hz/60Hz +/- 2%) for the drive's input stage.
• An internal sensor or monitoring circuit responsible for detecting the power supply characteristics on Port 3 has failed.
• Improper sizing or selection of the upstream power transformer or utility connection for the drive's Port 3 rating, causing over/undervoltage.

Click steps to track your progress.

1. 1

   1. Measure the line-to-line voltage (VAC) and frequency (Hz) of the power supply connected to drive input terminals R3/L1, S3/L2, T3/L3 using a digital multimeter.

2. 2

   2. Cross-reference the measured input voltage and frequency with the required specifications for Port 3 as listed in the drive's installation manual.

3. 3

   3. Confirm that the drive's Port 3 input is wired for the correct phase configuration (e.g., 3-phase) matching the incoming supply.

4. 4

   4. Physically inspect the input power wiring at terminals R3/L1, S3/L2, T3/L3 for any loose connections, miswiring, or signs of overheating.

5. 5

   5. If the drive has configurable input settings for Port 3 (e.g., Parameter P0-11 for voltage range), ensure they are set correctly via the HMI or software tool.
