12.4.13 Field wound DC motor wiring example
This diagram shows one potential way to wire the field supply if a field
wound DC motor is used.
▲ Danger of voltage
Removal of JP3 and JP4 removes the discharge resistor R2 from
the circuit. If no motor is connected, caution must be observed to
assure that no parts of the body come in contact with the high
voltage areas of the circuit board until the output circuit is fully
discharged.

• The 12 Vdc power supply needs to source at least 100 ma.
• F+, F- are the field connections to the field wound DC motor.
