Electro-mechanical brake
Connection of an electromagnetic brake is possible for all SK 1x5E devices. To control the brake, an output
voltage is generated to terminals 79 / 80 (MB+ / MB-) by the motor starter to terminals 79 / 80 (MB+ / MB-)
(also refer to Sections 2.6.1 to 2.6.2). This depends on the supply voltage. The assignment is as follows:
Mains voltage / Alternating current (AC)
Brake coil voltage (DC)
230 V ~
105 V =
400 V ~
180 V =
460 V ~ / 480 V ~
205 V =
The allocation of the correct brake or brake coil voltage must be taken into account in the design with refer-
ence to the mains voltage of the motor starter.
NOTE
For the connection of a mechanical brake to the terminals of the motor starter, parameters
P107 / P114 (brake application time / release time ) must be adjusted. In order to prevent
damage to the brake control, a value
≠ 0 must be set in parameter (P107).
The following settings for (P107/P114) are recommended for NORD brakes:
BRE5, BRE10, BRE40 :
0.02s,
BRE20, BRE60, BRE100, BRE150:
0.03s,
BRE250:
0.04s,
Connection terminals:
Screw terminals, 0.6 x 3.5 mm slot-head screwdriver
Connection cross-section: 0.2 ... 2.5mm
