*1. A recommended product is listed in 4-3,
Wiring Confirming 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 inductive load is 2 A (24 VDC).
*3. There is no polarity on the brakes.
*4. Models with a built-in Regeneration
Resistor (KN06F-ECT to KN20F-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.
