FAQ

Q: Is the pulse counting function of the NPCT-01C 64009486D used to connect to an encoder?
A: No. It is mainly used for closed-loop monitoring of the internal IGBT trigger pulses. External motor encoders are usually connected to a dedicated encoder interface board (such as NTAC).

Q: Why is timing accuracy so important for water-cooled inverters about NPCT-01C 64009486D?
A: Water-cooled inverters typically have extremely high power output and consist of multiple modules connected in parallel. If the timing of the NPCT board is off, it will cause uneven load on the modules, leading to localized overheating and burnout.

Q: Do I need to adjust the timing parameters after replacing the NPCT-01C 64009486D?
A: No. This board implements the reference timing through hardware circuitry. The specific control algorithm and timing constants are downloaded from the upper-level NAMC control board.

Q: Can I use an oscilloscope to measure the pulse signal of the NPCT-01C 64009486D?
A: Extremely dangerous. Because this board is directly connected to a high-voltage power circuit, a regular oscilloscope without isolation can easily cause electric shock or short circuit. It must be operated by a professional using a high-voltage isolation probe.

Q: Does the "C" suffix on this board improve timing performance about NPCT-01C 64009486D?
A: Performance remains the same, but the coating prevents leakage current from the circuit board due to moisture, thus ensuring that the waveform of the timing pulse is not distorted in high humidity environments.
