Normally B2 and B3 are short-circuited.
If there is high regenerative energy, remove the short-circuit bar
between B2 and B3 and connect an External Regeneration
Resistor between B1 and B2.
When using N terminal, make sure not to exceed the fuse's rated
voltage (660 VDC, 20 A).
Name
R88D-KNxF-ML2 (3 to 5 kW): 3-phase 380 to 480 VAC (323 to 528
V) 50/60 Hz
A Regeneration Resistor is not built in.
Connect an External Regeneration Resistor between B1 and B2, if
necessary.
Red These are the output terminals to the Servomotor.
Be sure to wire them correctly.
