Resistor braking
What this chapter contains
This chapter contains information about calculating the regenerative power created
by the motor when it decelerates or is driven by the load. The chapter then describes
the process for selecting an appropriate resistor to dissipate the regenerative power.
WARNING!
Electrical shock hazard. DC-bus voltages can be present at the
brake resistor terminals. Use a suitable heat sink (with fan if necessary) to cool
the brake resistor. The brake resistor and heat sink (if present) can reach
temperatures in excess of 80 °C (176 °F).
