*1. Recommended products are listed in
4-3 Wiring Conforming to EMC Directives
.
We recommend that you install two contactors to help prevent accidents that may occur due to
contact welding or other factors.
*2. Recommended Relay: OMRON G7T Relay (24-VDC model)
*3. An External Regeneration Resistor can be connected.
Connect this resistor if the regenerative energy exceeds regeneration absorption capacity in the
Servo Drive. (Refer to
Servo Drive Regenerative Energy Absorption Capacity
Note 1.
The dynamic brake operates when the main circuit power supply or the control circuit power
supply is turned OFF.
Note 2.
When turning OFF the main circuit power supply, turn OFF the RUN Command Input (RUN)
signal at the same time.
