The supply section supplies the inverter via the DC bus. The inverter
also takes energy from the DC busbars to make control voltages for the
control boards and auxiliary voltage for I/O board.
Voltage for inverter cooling fans for frame sizes R2i to R5i is taken from
the DC busbar. For larger frame sizes the cooling fan voltage is taken
from the 230/115 V a.c. transformer (in the Auxiliary Control Unit) via
thermal protection switch F10, F11 or F12 (depending on the frame
size).
The 24 V auxiliary voltage source is powered from a 230/115 V a.c.
transformer (in ACU) via F31 (or for frame sizes R7i and smaller via
F10).
The emergency stop and the optional uninterrupted power supply
(UPS) are wired from the Auxiliary Control Unit.
Drive section configurations are described below.
The drive section is equipped with DC fuses or a switch fuse with
charging circuitry (see below).
