Field circuit interfaces SDCS-BAB-F01 and SDCS-BAB-F02 (H1 ... H4)
The OnBoard field exciter is located internally. The firing pulses are synchronized using the mains
circuit L1, L2, L3 and the SDCS-CON-H01. The pulses are amplified on the SDCS-PIN-H01.
The hardware structure is a three phase half controlled bridge supplied directly from the mains U1,
V1, W1 via fuses F100, F101, F102.
If the OnBoard field exciter is not needed it can be deselected in the firmware.
The field circuit interface consists of:
– Firing the three phase half controlled field bridge.
– Measuring the field current on the DC side. The scaling is automatically selected using the rated
motor field current.
– The snubber circuit is shared with the armature bridge.
– Fuses F100, F101, F102 are used for cable and motor field winding protection.
– Size H3 and H4 converters for 600 V are always delivered without OnBoard field exciter.
– Size H5 converters do not use the field circuit interface on the SDCS-PIN-H01
