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.
These are the output terminals to the Servomotor.
Be sure to wire them correctly.
This is the ground terminal. Ground to 100 Ω or less.
