Type
1. Can be controlled using electrical signal.
Electrical signal can be used for “run”, “quick stop” and
“coast to stop” control of motors.
2. Operation time of the electric brake is adjustable.
Operation time is set to a suitable value within the range
from 0.1 to 2 sec
3. “Run” and “Instantaneous stop” lamps are provided.

Options
1. Compact 8P plug-in configuration.
2. Can be used in combination with other commercially
available SSR (contactless relay).
These combinations enable the use of electrical signals
for “run” and “quick stop” control of motors.
3. The electric brake operates for approx. 0.5 sec.
• These units are electric brakes that can stop motor immediately.
• These brake units are divided into the contact (separate) type and contactless (48 mm sq.(1.89 inch sq.)) type.
• Separate type brake units can be used with 3-phase motor.
• The contactless 48 mm sq.(1.89 inch sq.) type brake units can be used with induction motor, reversible motor and
electromagnetic brake motor.
Brake Unit
• These brake units are electric brakes used to
instantaneously stop motors.
• These electric brakes have longer life expectancy and
can perform inching operation.

• Names and functions
• Braking time control
Adjusts the time up to 2 sec (standard).
Since longer braking current increases
motor temperature, the shortest time
necessary to stop the motor is the
recommended setting.

[Notes]
1. Electric braking system has no holding torque.
2. For application requiring 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.

below when it is driven with WR (average on/off cycle power)
and 35% load factor.
Load factor = 35%
ON duration (braking time) = 1 sec
(fixed)
1. When 100 VAC supply WR = 476/(Toff + 1)
2. When 200 VAC supply WR = 571/(Toff + 1)
Example: 10 sec run; 5 sec stop; 1 sec braking; under 100 VAC
WR = 476 / [(10 + 5 + 1) + 1] = 31.7 W
