Motor will stop in time defined as in Parameter i.e. Ramp Down time OFF2: OFF-2 means Coast to Stop. Means drive will inhibit pulses and Motor will stop by it self with its own Inertia OFF3: OFF-3 also means Normal Stop but it will stop in time defined in Parameter for OFF3. Like P466 in Master Drive. Basically OFF-1 and OFF-3 will do same function but OFF-3 is generally defined for Emergency Stop. Drive will stop on OFF-3 on some fault to protect from high damage Regards, Devesh

Well, for OFF1 and OFF3 Brakes will be applied after ramp finished But incase of OFF2, brake will be applied as soon as OFF2 is active because in OFF2 drive disable pulses Regards Devesh
