Motor Starter ATS48 doesn't have a Relay output returning information about a Motor RUN or Motor Stopping status. Thus it can't control a mechanical motor break directly and workaround is to be applied.
This is a generic example of a possible ATS 48 wiring in combination with :
Non-reversing motor connection
with a line and a bypass contactor control
freewheel or controlled motor stop,
Type 1 coordination
Relay 1 is used in the Isolating relay (rII) mode. Like one, it will control the line contactor after receiving a RUN command and will be released at the end of braking or deceleration or when the motor switches to the freewheeling mode after a STOP command. It is also deactivated when a Fault occurs.
As a motor brake shall be released at the moment or just before RUN command and engaged after full motor stop, I think you can use this relay for brake control. As the relay has one contact only, an auxiliary relay to extend number of free NO contact is necessary.
