R88D-KNA5L-ML2/-KN01L-ML2/-KN02L-ML2/-KN01H-ML2
/-KN02H-ML2/-KN04H-ML2:
Normally, do not short B1 and B2. Doing so may cause malfunctions.
If there is high regenerative energy, connect an External
Regeneration Resistor between B1 and B2.
R88D-KN04L-ML2/-KN08H-ML2/-KN10H-ML2/-KN15H-ML2:
Normally B2 and B3 are shorted. Do not short B1 and B2. Doing so
may cause malfunctions. 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.
