Type code

The type code contains information on the specifications and configuration of the
regen supply module. The first digits from left express the basic configuration (e.g.
ACSM1-204AR-090A-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.

The ACSM1-204
Description
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.
Dissipates the braking energy by converting it to heat.
Energy storage which stabilizes the intermediate circuit DC voltage.
Converts the AC voltage to controlled DC voltage with IGBTs.
Smooths the line current waveform.
Converts the AC voltage to uncontrolled DC voltage with diodes. The rectifier is
not used for regenerative operation.
