Control Component Definition and Maintenance
Control Power Components There are two configurations for distributing control power for the drive,
dependent on your selected drive option.
• Direct-to-Drive™ (transformerless AFE rectifier) (see Figure 112
)
• AFE/18-pulse rectifier with separate isolation transformer (see Figure 113
on page 133)
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 112
illustrates the control power distribution for AFE drives with
integral starter and/or line reactor.
