*1. Recommended products are listed in 4-3,
Wiring Conforming to EMC Directives.
*2. Recommended relay: MY relay by
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).
*3. There is no polarity on the brakes.
*4.
The Regeneration Resistor built-in type
(KN20H-ECT-R) shorts B2 and B3. When
the amount of regeneration is large, remove
the connection between B2 and B3 and
connect the Regeneration Resistor between
B1 and B2.
