4.15.1 Feedback Termination

Connections for Feedback cables are different for each type of feedback device. Standard devices are: Resolver, Halls
(Hall Effect). Custom feedback devices are also available. Request a wiring diagram of your feedback device from the
manufacturer to determine the pin-out and/or wire color codes.
4.16 Optional Dynamic Brake Hardware
Refer to Figure 4-15 for DB resistor connections. Dynamic Brake (DB) Hardware must be installed on a fl at, non-fl ammable,
vertical surface for effective cooling and operation.

Before external Dynamic Brake Hardware is added, the internal resistor must be disconnected
(frames AA, B, C, and D). Remove the resistor from the B+/R1 and R2 terminals. The external
resistor can be connected across these terminals. Failure to remove the internal resistor will
decrease the total resistance (parallel connection) and cause damage.
