REGEN Resistor
If the motor is connected to a large inertia load that may require rapid
deceleration, an external REGEN resistor must be installed as follows:
1. Connect one wire from the REGEN Resistor to connector X1-7.
2. Connect the other wire from the REGEN Resistor to connector X1-8.
Resolver Wiring
The Resolver interface DB-9 connector is X8 on the DBSC control. Figure 3-5
shows the connector pin numbers and signal names. Use twisted pair shielded
cable with an insulated overall shield.
