Hi,
HY have always done their own thing, so some of what you learnt with the HY will have to be unlearnt for
the Altivar. Incidentally once you do learn you will find ALL the leading manufacturers excluding HY do very VERY
similar things.
On the Altivar there is a whole bunch of logic level inputs DI1, DI2, etc. They are digital inputs. You need to program
the VFD to tell it want you want each input to mean. For instance I see on the HY you have one FWD and one REV
input, you must program the Altivar to do the same.
Most market leading manufacturers have software meant to reside on your PC and connected to your VFD by a serial
cable to program the EPROM in the VFD. Does your device have it? If it does get it set up, programming by button pushing
is possible but an exercise in frustration.
