Command characteristic selection of master frequency
Range
0:
Positive characteristic (0-10V / 4-20mA = 0 -100%)
1:
Negative / inverse characteristic (0-10V / 4~20mA = 100 - 0%)
00-28= 0:
Positive reference curve, 0
– 10V / 4 – 20mA = 0 – 100% main frequency reference.
00-28= 1:
Negative reference curve, 0
– 10V / 4 – 20mA = 100 – 0% main frequency reference.
Note:
Selection applies to analog input AI1 and AI2.
