*1. Recommended products are 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 brake 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 (KP20H) 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.
