manual
SEW brake systems are DC operated disc brakes which are released electromagneti-
cally and applied by spring force. A brake rectifier supplies the brake with DC voltage.
The inverter switches the brake rectifier off in the AC circuit.
Always operate the brake via binary output DO02 of the inverter, not via the PLC!
Binary output DO02 is configured with a control voltage of +24 V / I
max
= 150 mA / 3.6
W for operating a relay. This relay can directly control a power contactor. This power
contactor engages and disengages the brake.

contactor
•
Only use supply system contactors in utilization category AC-3 (IEC 158-1).
•
Do not use the K11 supply system contactor for jog mode, but only for switching the
inverter on and off. Use the following commands for jog mode:
– Enable/stop
– CW/STOP
– CCW/STOP

07 is intended for operation on voltage systems with a directly grounded
star point (TN and TT systems). Operation on voltage systems with a non-grounded star
point (for example IT systems) is permitted. In such a case, SEW recommends using an
earth-leakage monitor according to the PCM (pulse-code measurement) principle.
Fuse and core
cross section
Comply with the regulations of the specific country and for the specific machine regard-
ing fusing and selecting the line cross sections.
Select the line cross section of the motor lead so the voltage drop is as small as possible.
Route a separate supply system lead for the brake rectifier when operating with an in-
verter. Powering it from the motor voltage is not permitted! See the wiring diagram!
Recommendation
Observe a minimum switch-off time of 10 s for the supply system contactor K11.
