Baldor mn1854 manual Interlock Intlk, Ground GND, Motor Connector

Motor Connections The A+, A–, B+ and B– phase outputs of each axis provides power to the motor windings. The location for each motor connector (Bottom Panel) is shown in Figure 3-4. The motor windings can be connected in series or parallel as shown in Figure 3-14. For Baldor motors, refer to MN1800 for lead information.

Interlock (INTLK)

The two INTLK pins for each motor connector must be jumpered for the drive to apply power to the motor. If an interlock wire breaks, or the connector is removed, motor current is immediately stopped, the drive faults (latched) and flashes the dual function LED labeled Over Volt./INTLK. Interlock wires longer than 5 inches can create shutdowns due to noise.

Ground (GND)

GND is internally connected to the Earth pin on the Power connector. This provides a convenient terminal for grounding the motor frame and a motor cable shield.
