Control cables
*1. Recommended products are listed in 4-3
Wiring Conforming 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 induction load
is 2 A (24 VDC).
*3. There is no polarity on the brakes.
*4. Provide auxiliary contacts to protect the
system with an external sequence so
that a Servo ON state will not occur due
to deposition in the Dynamic Brake
Resistor.
*5. Use an external Dynamic Brake Resistor
of 1.2 Ω, 400 W.
*6. Install an external protective device,
such as a thermal switch. Monitor the
temperature of the external Dynamic
Brake Resistor.
