OMRON (24-V) For example, MY2
relay by OMRON can be used with all
G5-series motors with brakes because
its rated induction load is 2 A (24 VDC).
Resistor (KN20H-ECT) have B2 and
B3 shorted. When the amount of
regeneration is large, remove the
connection between B2 and B3 and
connect a Regeneration Resistor
between B1 and B2.
