Component Definition and Maintenance Chapter 5
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. Line Reactor Drive (refer to Figure 267 )
2. Remote Transformer and Starter (refer to Figure 268 )
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 267 illustrates the control power distribution for 6-pulse and PWM drives
with integral starter/line reactor.
Figure 267 - AFE Line Reactor Drives
Figure 268 illustrates the control power distribution for 6-pulse and AFE drives
with remote transformer/starter or integrated line reactor with remote starter.
