Internal power distribution source for manual speed control potentiometers.
Many technicians skip the manual and try to reverse-engineer the board. This leads to three common mistakes:

If you still face issues not covered here, consult the warranty card or contact technical support with your exact model number and firmware revision (visible during power-on self-test).
The is a high-voltage, high-efficiency Brushless DC (BLDC) motor driver engineered for precision control of medium-power industrial motors. Operating on an integrated high-voltage DC bus (typically 310V DC derived from a 220V AC input), it supports motors up to 1100W with a maximum current threshold of 5A .

Older power supplies from the 1980s were often heavy "linear" supplies (containing massive transformers). They were reliable but ran hot, were heavy, and eventually dried out the capacitors.
Enable Signal (Stop/Run) – Connect to COM to stop, disconnect to run (or via switch).
Always disconnect power before wiring.
