Control Power Components There are two configurations in which control power will be distributed
for the drive. The different methods are dependent on what drive option
the customer has chosen:
1. AFE Rectifier with DTD DC Link – Conf. #1 (refer to Figure 5.44)
2. AFE Rectifier with Separate Isolation Transformer – Config. #2
(refer to Figure 5.45)
3. AFE Rectifier with Integral Isolation Transformer – Config. #3
(refer to Figure 5.45)
Ride-Through
Standard controls with 5 cycle ride-through – The drive main control
boards will remain energized for a total of 5 cycles after control power is
interrupted. If control power is not restored during the 5 cycles, a
controlled shutdown will occur.
Figure 5.44 illustrates the control power distribution for AFE drives with
integral starter/line reactor.
