1.6 Definitions

Frequency converter
I
VLT,MAX
The maximum output current.
I
VLT,N
The rated output current supplied by the frequency
converter.
U
VLT, MAX
The maximum output voltage.
Input
The connected compressor
can start and stop with LCP
and the digital inputs.
Functions are divided into 2
groups.
Functions in group 1 have
higher priority than
functions in group 2.
