*1. A recommended product is listed in 4-3,
Wiring Confirming to EMC Directives.
*2. Recommended relay: MY relay by
OMRON (24-V type) 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
(KN08H-ML2 to KN15H-ML2) 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.
