Wiring the Dynamic Brake Circuit
This section shows how to wire the dynamic brake based on a wiring example that uses the
recommended parts from the following section.
Selecting the Magnetic Contactor and Relay
The /DBON (Dynamic Brake Operation Request Output) and /DBANS (Dynamic Brake Answer
Input) signals must be allocated to sequence I/O signal terminals.
Note: 1. Separate the 24-VDC power supply for the Magnetic Contactor from the power supply for the I/O signals
(CN1). If the same power supply is used, the I/O signals may malfunction.
2. The recommended relay (G6B-4BND) is a terminal relay equipped with four mini-relays. A single relay can
be used for Relay1 and Relay2 in the above diagram.
