2.7.4
Electro-mechanical brake
An output voltage is generated by the frequency inverter on terminals 79 / 80 (MB+ / MB-) of the control
terminal block for the control of an electromechanical brake (See also Section 2.8.1 and 2.8.2). This
depends on the supply voltage of the frequency inverter. The assignment is as follows:
Mains voltage / Alternating current (AC) Brake coil voltage (DC)
115 V ~ 105 V =
230 V ~ 105 V =
400 V ~ 180 V =
460 V ~ 205 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.
2.7.5
Mains supply jumpers
These jumpers are used to adapt the SK 200E to various forms of mains supply (e.g. IT network). As
supplied, a star configuration earthed mains supply must be used, with an earth conductor for single phase
devices.
To adapt the SK 200E to an IT network, the capacitors C
y
must be disconnected from earth. This is carried
out by changing a jumper position as shown in the diagram.
Here it must be noted that the specified degree of radio interference suppression changes. Further details
can be found in Section 9.3 EMC.
