If the preceding wiring method is used, you need to allocate a certain DI (for example, DI1)
of the drive with the function of external fault NO input. Take Inovance IS300 servo drive
as an example; to allocate DI3 with the function of external fault NO input, set F4-02 to 11.
When you use the drive of other companies, perform the setting according to the user
manual of this drive.

The preceding wiring method is used when multiple braking units are connected in parallel.
The wiring between the braking unit and the braking resistor is not shown in the figure.
The input voltage class of the contactor control coil is 220 VAC.
When multiple braking units are connected in parallel, set one braking unit as the master
(P0-03 = 0), and set all other braking units as the slave (P0-03 = 1).
Set the same braking start voltage (P0-00), braking stop voltage (P0-01), and start braking
rate (P0-02) for the master and all slaves.
