14.OPTIONS AND AUXILIARY EQUIPMENT

(4)Connection of the regenerative brake option

The regenerative brake option will generate heat of about 100. Fully examine heat dissipation, installation position, used cables, etc. before installing the option. For wiring, use flame-resistant cables and keep them clear of the regenerative brake option body. Always use twisted cables of max. 5m(16.4ft) length for connection with the servo amplifier.

(a)MR-J2S-350CL or less

Always remove the wiring from across P-D and fit the regenerative brake option across P-C.

The G3 and G4 terminals act as a thermal protector. G3-G4 are disconnected when the regenerative brake option overheats abnormally.
