I2 Incompat PS

What does 10232 mean?

The drive has detected an incompatible power supply for the drive AC input rating on port 2. This can lead to improper operation or damage if not addressed.

• The voltage of the power supply connected to Port 2 is outside the drive's permissible operating range (e.g., input phase voltage measured at 200VAC when expecting 400VAC).
• Incorrect phase sequencing or phase count (e.g., three-phase supply connected to a drive configured for single-phase on Port 2) for the specific drive unit.
• Frequency deviation of the input power at Port 2, exceeding the +/- 5% tolerance of the drive's nominal input frequency.
• Damage or malfunction of the voltage sensing circuit specifically for input Port 2 on the drive's main control board.
• External power factor correction or harmonic filtering equipment on Port 2 that is not compatible with the drive's input characteristics or causes voltage distortion.

1. 1

   1. Measure the line-to-line voltage (VAC) and frequency (Hz) of the power supply connected to drive input terminals R2/L1, S2/L2, T2/L3 using a calibrated multimeter.

2. 2

   2. Refer to the drive's nameplate and technical specifications to confirm the correct input voltage and frequency requirements for Port 2.

3. 3

   3. Verify that the incoming power supply's phase configuration (e.g., 3-phase Delta, 3-phase Wye) is consistent with the drive's Port 2 specifications.

4. 4

   4. Inspect all power connections at Port 2 for secure termination and correct wiring scheme, paying attention to R2, S2, T2 terminals.

5. 5

   5. If an input reactor or filter is installed on Port 2, verify its rating matches the drive and that it is correctly installed according to the manufacturer's guidelines.
