Operation
This table describes the operation of the main circuit in short.
Type code
The type code contains information on the specifications and configuration of the
drive. The first digits from left express the basic configuration (e.g. ACSM1-04AS-
09A5-4). The optional selections are given thereafter, preceded by + signs (e.g.
+L501). The main selections are described below. Not all selections are necessarily
available for all types; refer to
ACSM1 Ordering Information , available on request.

Component Description
Braking chopper Conducts the energy generated by a decelerating motor from the DC bus to a
braking resistor. The braking chopper is built in the ACSM1; braking resistors
are external options.
Braking resistor Dissipates the regenerative energy by converting it to heat.
Capacitor bank Energy storage which stabilizes the intermediate circuit DC voltage.
Inverter Converts the DC voltage to AC voltage and vice versa. The motor is controlled
by switching the IGBTs of the inverter.
Mains choke See page 85 .
Mains filter See page 87 .
Rectifier Converts the three-phase AC voltage to DC voltage.
