(3) Connecting with the servo drive unit
Correctly wire the dynamic brake unit to the servo drive unit.
Do not use for applications other than emergencies (normal braking, etc.). The internal resistor could
heat up, and lead to fires or faults.
When you use a motor with a brake, please wire (between 1pin and 3pin) for the CN20 connector.
