Indicates that the electric brake is being applied. Indicates that the motor is operating. Indicates that current is flowing through the electromagnetic brake. (Brake is released as the electromagnetic brake is energized.) Adjust the application time of electric brake according to inertia of the load. Standard setting is 0.2 sec (recommended) 1 W to 25 W 40 W to 90 W Low For motor of 1 W to 25 W For motor of 40 W to 90 W To reduce impact during braking with motor of 1 W to 90 W • Outline drawing 69.2(2.72) 5.5(0.22) 48 mm sq.

Part No. For reversible motor Index Item For induction motor Options • Specification Brake Unit • Maintenance-free Unlike a relay control panel, wiring is not necessary. Contactless configuration requires no maintenance. • Various motor capacities can be selected. Can support 1 W to 90 W motors. With 40 W or larger motors, selection can be made with the brake torque switch. Brake resistor is not required and wiring is simplified. • Easier standardization of panel design Control panel can be sized to DIN standard at lower total cost. • Various options One option, mounting frame, for example, allows installation of the unit on the panel. • Soft-braking capability The brake torque switch has “LOW” position. In this position, the brake torque is reduced. • Braking time Time is simply adjustable from the selector switch.

Electric braking system has no holding torque. 2. Reversible motor is provided with a simple constant sliding brake with slight holding force. For application requiring larger holding force, use Panasonic electromagnetic brake motor. 3. When braking a load with excessively large inertia, related issues are strength and life of motor shaft and gear. For these subjects, consult us. 4. When using motor other than compact geared motor, consult us. * Please read your User's manual carefully so that you will understand the operation and safety precautions before attempting to operate the system.
