When operate in CV mode, the VFD displays CV mode.
There are three voltage ranges for CV operation: high voltage range, middle voltage range,
and low voltage range. The current is always in high range. ALL voltage levels are
programmed in V. The following examples show how to set the CV values of Load module
for model 63630-80-60.
1.
Select Range
Select proper range, by pressing
RANGE
the
key is lights up. High range is used when higher voltage level is required,
and LOW range is used when better resolution is required.
