Note - these are the external brake resistor accessories that can be used if more regeneration power dump capability is required than the drive's internal dump resistor provides.
APCS-140R50 (140W / 50 Ohm) - generally used with the 400W drive level
APCS-300R30 (300W / 30 Ohm) - generally used with the 1kW drive level
APC-600R30 (600W / 30 Ohm) - generally used with the 3.5kW drive level
(note - user guide shows this ordering number as APCS-600R30 but it is actually APC-600R30 at this time)
