ð p. 17
l
B6 bridge rectifier, integral supply filter and soft-start circuit
l
Single-phase supply operation possible (e.g. for setup)
l
Fusing (e.g. fusible cutout) to be provided by the user
l
Shielding All shielding connections are made directly on the amplifier
l
Output stage IGBT module with floating current measurement
l
Regen circuit with dynamic distribution of the regenerated power between
several amplifiers on the same DC bus link circuit. Internal
regen resistor as standard, external regen resistors if required.
l
DC bus link voltage 135 … 450 V DC or 260 … 900 V DC,
can be connected in parallel.
l
Interference suppression filters are integrated for the electrical supply feed and the
24V auxiliary supply voltage (with motor cable £ 10m for general availability as per
EN 61800-3, with motor cable < 10m for 2nd environmental category as per EN
61800-3).
