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).
The model GT75H does not have a built-in
regeneration resistor. If the amount of
regeneration is large, an External
Regeneration Resistor must be connected to
B1-B2.
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.
Recommended products are listed in 4-3
Wiring Conforming to EMC Directives.
