6. OPTIONS AND AUXILIARY EQUIPMENT
(3) Connection of the regenerative brake option
When using the regenerative brake option, always remove wiring from
across P-D and install the regenerative brake option across P-C. Set
parameter No.0 according to the option to be used. The regenerative
brake option will generate heat of about 100°C. Fully examine heat
dissipation, installation position, used cables, etc. before installing
the option. For wiring, use fire-retarding cables and keep them clear
of the regenerative brake option body. Always use twisted cables of
max. 5m length for connection with the servo amplifier.
