2.1.2. Motor Supply Connector
Motor power is applied to the
B+
,
B-
, and
RET
terminals of the Motor Supply connector. To improve
thermal performance of the amplifier, you should use the lowest motor supply voltage that you need
for your application. The
B+
and
B-
inputs are connected to internal fuses. Refer to
for the
internal fuse values and part numbers. For an isolated DC supply, connect
RET
to protective ground
at the supply. Use twisted pair wiring to minimize radiated noise emissions (refer to
).
IMPORTANT
: Refer to local electrical safety requirements to correctly size external
system wires.
