Brakemotors with incorporated brake
Brake connection via motor winding
Y circuit
Terminals 1-2 can be connected directly to the
motor terminals to supply the brake. Compare
the motor/brake voltages to determine whether
the connection is to be made on U1-U2 or U1-
V1.
Terminals 3-4 must be bridged.
Y circuit
Brake
An external power supply can be applied on
terminals 1-2. Check the voltage data on the
rating plate. Terminals 3-4 must be bridged.
For a rapid engagement of the brake (DC-
voltage side tripping) bridge 3-4 can be re-
placed by a contact. The contact must be
tripped simultaneously with the brake power
supply.
∆
circuit
In order to provide for the emergency venting
of the brake, e.g. to turn the motor manually,
you can apply a DC voltage source to terminal
1-4 (remove any other wiring before hand and
observe the polarity).
U voltage = = U~ x 0.45
U voltage~see brake voltage on the rating
plate.
