*1. A recommended product is listed in 4-3,
Wiring Confirming to EMC Directives.
*2. Recommended relay: MY relay by
OMRON (24-V)
MY2 relay by OMRON can be used for a
rated inductive load of 2 A (24 VDC).
*3. When using an externally connected
Dynamic Brake Resistor, remove the
short bar from between DB3 and DB4.
*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. A Dynamic Brake Resistor of 2 Ω, 180 W
is built in. If the capacity is insufficient,
use an external Dynamic Brake Resistor
of 1.2 Ω, 400 W. Do not use the built-in
resistor and an external resistor at the
same time.
*6. Install an external protective device, such
as a temperature fuse. Monitor the
temperature of the external Dynamic
Brake Resistor.
