I.5.1 04S functional units
The following circuit sections are built onto a single Eurocard, 199x100x12TE with
SMD-technology:
n
3-phase power supply with smoothing capacitors (-P-)
n
single phase supply (any phase with the rated voltage, possibly with extra
smoothing capacitance) is possible
n
fuses for DC-link, ballast circuit and auxiliary power supply
n
ballast circuit with -w- characteristic
n
4-quadrant output stage (V-MOS transistors)
n
auxiliary supply, optionally (solder links) supply from the DC-link
or an external 24 V DC source
n
2 differential setpoint inputs
n
input for DC tacho
n
Enable input
n
limit-switch inputs positive / negative
n
integral-off input for driving up to a fixed stop
n
