Drive load specifications
Specification
Options
Name
Any text or number string. This will also
show up in reports and, depending on
the Tools/Options settings, on screen.
Inverter amount
Number of similar drives with range 1 –
100 for one branch in the System
configuration tree
Type
Air cooled, Cold plate
IP class
Not specified
IP20 – This selection means that the
user is specifically limiting the choices
to the IP20 protection class.
Switching frequency
4, 8, 16 kHz. Higher switching
frequency will reduce the audible noise
and give better motor performance, but
will adversely cause losses in the drive
and the max current providing
capability.
Braking chopper
Ignored – This selection means that
even though the internal chopper is
used, the losses of it are anyway
ignored when a drive selection is
performed.
Internal – This selection means that the
losses of internal chopper are added to
drive losses and the limitations of the
internal chopper are considered when
selecting a drive.
Braking resistor
Not considered – The braking resistor is
not selected this time.
Selected – The braking resistor is
selected on the basis of the motion duty
braking power requirements.
