50 to 400 W: These terminals normally do not need to be connected. If there
is high regenerative energy, connect an External Regeneration Resistor
between B1 and B2.
750 W to 1.5 kW: Normally B2 and B3 are shorted. 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.
Red These are the output terminals to the Servomotor.
Be sure to wire them correctly.
