1.1.1 Frequency Converter
I
VLT,MAX
Maximum output current.
I
VLT,N
Rated output current supplied by the frequency converter.
U
VLT,MAX
Maximum output voltage.

1.1.2 Input

Control command
Start and stop the connected motor with LCP and digital
inputs.
Functions are divided into 2 groups.
Functions in group 1 have higher priority than functions in
group 2.
