Input
4 4 Process value input
Enter the 4 to 20mADC process value signal
from the detector.
FUP Upper limit output
Output to indicate that the process value
signal exceeded the upper limit value.

output
"Hi" is output to indicate that the output
indication of the parameter unit is forward
rotation (FWD) or "Low" to indicate that it is
reverse rotation (REV) or stop (STOP).

Enter the set point across inverter terminals 2-5 or in Pr. 133 and enter the process
value signal across inverter terminals 4-5.
Item Entry Description
Set 0V as 0% and
5V as 100%.
When "0" is set in Pr. 73 (5V
selected for terminal 2).
Set point Across terminals 2-5
Set 0V as 0% and
10V as 100%.
When "1" is set in Pr. 73 (10V
selected for terminal 2).
Set point Pr. 133 Set the set point (%) in Pr. 133.
Process value Across terminals 4-5 4mA DC is equivalent to 0% and 20mA DC to 100%.
