1.1.6 Definitions
Drive:
I
VLT,MAX
The maximum output current.
I
VLT,N
The rated output current supplied by the Adjustable
frequency drive.
U
VLT, MAX
The maximum output voltage.
Input:
Control command
Start and stop the
connected motor with the
LCP or the digital inputs.
Functions are divided into
two groups.
Functions in group 1 have
higher priority than
functions in group 2.
