Control Power Components
There are two configurations for distributing control power for the drive,
dependent on your selected drive option.
• Line Reactor Drive (refer to
Figure 77 )
• Remote Transformer and Starter (refer to
Figure 78 on page 104 )
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 interruption. If you
cannot restore control power during the 5 cycles, the drive performs a controlled
shutdown.
Figure 77 illustrates the control power distribution for PWM drives with integral
starter/line reactor.
Figure 77 - AFE Line Reactor drives
Figure 78 illustrates the control power distribution for AFE drives with remote
transformer/starter or integrated line reactor with remote starter.
