How to activate Run command on Altivar 212 frequency inverter when an Analog input exceeds its threshold?
It is possible in combination with one real output that will be assigned to function 62 (relay energizes when analog input VIA exceeds a threshold). Then relay output if hardwired to logic input assigned to run forward command (F terminal by default) will control run command.
Configuration example for VIA and relay RY, run command activated VIA exceeds 6V run command deactivated when VIA goes below 5V
F130=62
F160=55% (threshold) of 10V
F161=5% (hysteresis) of 10V
Besides that, the same analog input can also be used as a speed reference. Bear in mind the scaling, e.g. F201-F204 for VIA signal.
