Adjustable Frequency 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 Group 1 Reset, Coasting stop, Reset
Start and stop the
connected motor with
the LCP or the digital
inputs.
