*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 (KN04L-ECT,
KN08H-ECT, KN10H-ECT and KN15H-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.
*5. There is no Internal Regeneration Resistor for KNA5L-ECT
to KN02L-ECT, and KN01H-ECT to KN04H-ECT. When
the amount of regeneration is large, connect the necessary
Regeneration Resistor between B1 and B2.
