3.1 Drive system topology
The ACS6000 drive system consists of the following components:
• Main circuit breaker: For more information, see “2.8 Maintenance
recommendation” on page 49.
• Input transformer: Required if the line voltage must be adapted to
the motor voltage. For more information, see the “Main
transformer specification”.
• Drive
• Motor
3.1.1 Drive
The ACS6000 is a voltage source frequency converter for high-power
induction and synchronous motors. The drive features a common DC bus
permitting the configuration of single-motor or multi-motor solutions.
