Hello all,
First time having to work with a braking motor. i have attached the motor nameplate and schematic wiring. The motor is being replaced and i want to make sure i'am doing it correctly. The motor controls a sheet dispensers up/down movement. The motor is being controlled by two PLC outpus, one for up and one for down, wired into an allen bradley reversing starter typical setup,their is an AUX Normally open contact from both starters that is wired to another relay, lets call this the brake relay (relay that controls the on/off of the brake on the motor) that should energize/denergize the brake in the motor. The purpose of the Aux normally open contacts is when either of the starters pull in for up/down the normally open will be normally closed their by energizing the brake relay which which should inturn release the motors brake. The brake relay has 1 dry NO contact, and i want to know where to wire it in to the terminals of the braking motor to achieve what i have described.
I have the windings wired for low voltage, based on the schematic terminals A & B look like the supply for the brake. So if i wire leg 7 to terminal A then have a wire go to one end of the normally open contact of my brake relay then have the other end go to B i think i can achieve what i want, sounds simple, but i just want to be sure. Also if someone with knowledge of Bobine/coil can explain to me what that is i'd appreciate it, and yes i googled it, i didn't find anything credible.
