2.4.2.4 Electromechanical brake
Only valid for SK 2x5E size 1 - 3 and SK 2x0E size 4:
The device generates an output voltage at terminals 79 / 80 (MB+ / MB-) for actuating an
electromagnetic brake. This is dependent on the supply voltage present at the device. The allocation
is as follows:
Mains voltage / AC voltage Brake coil voltage (DC)
115 V ~ / 230 V ~ 105 V =
With the SK 2x5E, the connecting terminals are on the control terminal block, and with the SK 2x0E,
size 4 they are separate from this to a certain extent.

The assignment of the correct brake and brake coil voltage must be taken into consideration in the
design with regard to the mains voltage of the device.
For the connection of an electro-mechanical brake to the terminals of the device, parameters P107 / P114 (brake
application time / release time ) must be adjusted. In order to prevent damage to the brake control, parameter
(P107) must contain a non-zero value.
