*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
(KN30F-ECT-R and KN50F-ECT-R) connects
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.
