: Connects to the main power supply via the emergency stop switch.

: Often integrated with a separate forward/reverse switch to swap polarity to the motor. Common Components in the Schematic

Labeled A- and A+ for connection to the DC brush motor. Reversing these leads will reverse the motor direction.

To verify if a failure belongs to the board or the motor, disconnect the motor and apply a safe, low-voltage external DC source (like a

: Terminals labeled I1 and I2 can be used to electronically reduce output to zero. On-Board Trimpot Adjustments

: 0–90V DC (for 110V units) or 0–180V DC (for 220V units). Current Rating : Typically 12A to 13.5A DC.
