high reference value.
6-22 Terminal 54 Low Current 0–20 mA 4 Enter the current that corresponds to the high
reference value.
6-23 Terminal 54 High Current 0–20 mA 20 Enter the current that corresponds to the high
reference value.
6-24 Terminal 54 Low Ref./Feedb.
Value
-4999–4999 0 Enter the feedback value that corresponds to
the voltage or current set in 6-20 Terminal 54
Low Voltage/6-22 Terminal 54 Low Current

voltage input.
20-81 PI Normal/ Inverse Control [0] Normal
[1] Inverse
0
Select [0] Normal to set the process control to
increase the output speed when the process
error is positive. Select [1] Inverse to reduce
the output speed.
