Installation
Remark
Switch Main Contactor (K1) On and Off is controlled
by digital output DO5. In case of Emergency Off the
Main Contactor is controlled by the Emergency Off
button and can switched off at any time. Under load
condition that produce sparking on Main Contactor
which produce high voltage when the sparking goes
out. To protect the converter against high voltage a
Varistor MOV S20K625 is needed in parallel to the DC
terminal block C1 / D1.
In all cases of Emergency Off the drive trips with fault
because the armature circuit is open.
