A.1.4 Regeneration resistors
Depending on the application, MicroFlex might require an external regeneration resistor to be
connected to pins R1 and R2 of connector X1. The regeneration resistor dissipates energy
during braking to prevent an over-voltage error occurring. See sections 3.6 and 3.7 for details
about choosing the correct resistor .
WARNING: Electrical shock hazard. DC bus voltages may be present at these
terminals. Use a suitable heatsink (with fan if necessary) to cool the
regeneration resistor . The regeneration resistor and heatsink (if present)
can reach temperatures in excess of 80 °C (176 °F).
