Notes:
1. When the braking is frequently applied, please increase the resistor wattage
and add the cooling fan to prevent the resistor from overheating.
2. Aluminum case resistors have the better thermal performance. Please select
1.2 times rated power resistor by using general wirewound type resistor.
3. Please use the heat-resistant wire for the brake resistor wiring.
DANGER
When the dynamic brake unit is fault, the braking transistor maybe turn on for
full cycle. Add the thermal protection device to cut off the power at high
temperature to avoid the drive burnout (refer to the section f of Appendix D for
wiring of braking resistor).
