Hi, Visco
You described the algorithm of the system with a VFD. I usually use the VFD internal option to control the brake.
The brake active when the VFD reaches zero speed and there is no command to move in the forward or reverse direction. This eliminates the problems of controlling the VFD in different modes, for example, JOG, FIXED SPEED.
No need to control the brakes with the PLC. This is especially useful when lifting or lowering some part of the mechanisms.
However, the VFD must be able to control the brakes.
