Resistor connection
terminals
50 to 400 W: Normally, do not short B1 and B2. Doing so may result in
malfunctioning. 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. Do not short B1 and B2.
Doing so may result in malfunctioning. 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.
