2.7.4 Electromechanical brake (only SK 2x5E)
Connection of an electro-mechanical brake is possible for all SK 2x0 devices above S 4 and all SK 2x5E
devices. For the control of the brake, the frequency inverter generates an output voltage on terminals 79 /
80 (MB+ / MB-) of the control terminal strip (SK 2x0E, S 4: separate terminal block, see illustration below),
(see also Section 2.8.1 to 2.8.3). This is dependent on the supply voltage present in the frequency inverter.
The allocation is as follows:
Mains voltage / Alternating current (AC) Brake coil voltage (DC)
115 V ~ / 230 V ~ 105 V =
400 V ~ 180 V =
460 V ~ / 480 V ~ 205 V =
The assignment of the correct brake or brake coil voltage must be taken into account for the design related
to the mains voltage of the frequency inverter.
NOTE
For the connection of a mechanical brake to the terminals of the frequency inverter,
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,
