Ground to 10 Ω or less.
*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 Built-in Regeneration Resistor
(KT30F and KT50F) 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.
