Recommended products are listed in 4-3
Wiring Conforming to EMC Directives.
Also, to ensure safety (i.e., to ensure that
the power supply can be shut OFF) for
contactor welding, we recommend using
two magnetic contactors (MC).
Recommended relay: MY Relay (24 V),
by OMRON. For example, the MY2
Relay's rated inductive load is 2 A at 24
VDC and applicable to all G-Series
Servomotors with brakes.
The brake is not affected by the polarity
of the power supply.
Connect B2-B3 for the models with a
built-in regeneration resistor (GT20H to
GT50H). If the amount of regeneration
is large, disconnect B2-B3 and connect
an External Regeneration Resistor to
B1-B2.
