Hi everyone
i have a delta VFD ,it's control signal is from 0..10V or in Mamps (no -10..10v)
my plc is 1251dc/dc/rly with analog output 0..20ma , i have used a 500ohm resistor to get the 10V
in order to use the motion control is it a must to have a VFD of -10..10V analog input and a plc of the same voltage rang -10..10V
in the vfd there is something called BIAS which give a result of (0 to 5V CW 5 to10 CCW)
can i use this feature instead of -10..10V
kind regards
