A.1.5 Regeneration resistors
Depending on the application, MicroFlex e100 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 .
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 heat sink (if present) can reach temperatures in
excess of 80 °C (176 °F).
