Note : 1. Brake type may differ depending on specification. Check the nameplate.
2. Brake torque will change according to operating environment, operating conditions, the condition of the friction surface, etc. In
particular, brake torque may not be at the prescribed level for initial operation, and after a long period of inactivity. In such a case
turn the brake on and off under as light load as possible to contact the brake’s friction surfaces.
3. Brake activation delay time will change according to the brake’s wiring circuit. Select the optimum circuit for the application.
