Table 2.3/2: Definition of the load cycles
If the driven machine’s load cycle does not
correspond to one of the examples listed, you
can determine the necessary power converter
DCSize
using the
software program.
This program can be run under Microsoft
dows, and enables you to dimension the motor
and the power converter, taking types of load
(load cycle), ambient temperature, site elevation,
etc. into account. The design result will be
presented in tables, charts, and can be printed out
as well.
To facilitate the start-up procedure as much as
possible, every power converter has been pro-
vided with a current measuring feature, which
can be adjusted to the high current required by
means of software parameters.
