Overview
Mounted holding brake for 1PH8 motors
A brake can be mounted on the DE of 1PH808 to 1PH822
motors.
These brakes are electromagnetic units for dry-running opera-
tion. An electromagnetic field is used to release the brake which
is applied using spring force. They operate in accordance with
the quiescent current principle, i.e. when no current is flowing,
the spring-operated brake brakes and holds the drive. When
power is applied to the brake, it is released and the drive is free
to rotate.
In the event of a power failure or an emergency stop, the drive is
braked from its current speed down to standstill.
Connection of the brakes (must be provided by the customer)
•
Alternating voltage 230 V 1 AC, 50/60 Hz
•
Direct voltage 24 V DC up to 1PH816
The brake module is designed for an ambient temperature of
-5 °C to +40 °C (23 °F to 104 °F).
The maximum speed of a motor with brake is limited to the
maximum speed of the brake (refer to the table).
The holding brakes for 1PH818 and 1PH822 are not UL-ap-
proved. As a consequence, these motors do not have the cUR
marking when mounted on brakes.

Holding torque
For 1PH810 to 1PH816 motors, the holding torque
can be continuously set in the specified value range
using a setting ring. The dynamic braking torque is
approximately 70 % of the set holding torque.
