Operation
Size the dynamic brake resistor according to the motor current rating (see the table below).
The dynamic brake resistance listed in the table is the smallest recommended resistance
allowed to prevent possible demagnetization of the motor. The motor stops less rapidly
with higher brake resistor values.

For motors rated 1/17 horsepower and lower, a brake resistor is not necessary since the
armature resistance is high enough to stop the motor without demagnetization. Replace
the dynamic brake with 12 gauge wire.

WARNING
Wait for the motor to completely stop before switching it back to RUN. This will prevent
high armature currents from damaging the motor or drive.
