Connect B2-B3 for the models
with a built-in regeneration resistor
(GN20H-ML2 to GN50H-ML2).
If the amount of regeneration is large,
disconnect B2-B3 and connect an
External Regeneration Resistor 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.
