Permitted brake controls
INFORMATION
The following specifications refer to motors designed for operation at ambient tem-
peratures of -20 °C to +40 °C, and with thermal class 130 (B) or 155 (F). Deviations
may occur depending in the installed motor options.
In individual cases, always also observe the additional specifications in the order con-
firmation and on the motor nameplate.
The brake is designed for operation with AC voltage or DC voltage, depending on the
design. A brake control by
SEW‑EURODRIVE
is used that is either installed in the mo-
tor terminal box (category 3D) or in the control cabinet (category 3G, 3GD).
BE03 – 2 brakes can also be operated without brake control by
SEW‑EURODRIVE
with DC voltage. Observe the information on the motor nameplate. In this case, a suit-
able overvoltage protection must be installed at the terminal strips in the terminal box
using varistors. The varistors are not included in the delivery of the motor.
The following brake control types are not permitted:
•
Operation with AC voltage without brake control by
SEW‑EURODRIVE
with
BE03 – BE122 brakes.
•
Operation with DC voltage without brake control by
SEW‑EURODRIVE
with BE5 –
BE122 brakes.
•
Operation with third-party brake control systems.
For an overview of available brake controls by
SEW‑EURODRIVE
and of the technical
data, refer to the chapter "Brake control" (→
196).
WARNING
Severe or fatal injuries
Great and unexpected elongation of the stopping distance.
•
Operate each brake with a separate brake control.
•
Observe
the
notes
on
dimensioning

the
catalog,

5.16.3
Optional separation of DC and AC circuits
In case of brakes operated with AC voltage, make sure the disconnection type desig-
nated by the manufacturer is applied correctly during the brake connection. The fol-
lowing types are distinguished:
•
Cut-off in the AC circuit with normal application time
•
Cut-off in AC circuit and DC circuit with shortened application time
The correct switch-off type must be ensured by a respective wiring. Certain brake con-
trols by
SEW‑EURODRIVE
implement the same AC and DC cut-off via integrated
switching relays (e.g. BMP1.5), or via mounted relays (e.g. BSR or BUR for category
3D).
The switch-off type is specified on the included wiring diagrams by a pictogram.
