input
Enter the 4-20mADC process value signal from
the detector.
Pr. 128 = 20, 21
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).

#
To start PID control or Advanced PID control, switch on the X14 signal. When this signal is off, ordinary
inverter operation is performed without the PID action being done.
#
Enter the set point across inverter terminals 2-5 or into Pr. 133 and enter the process value signal across
inverter terminals 4-5. At this time, set "20" or "21" in Pr. 128.
#
When entering an externally calculated deviation signal, enter it across terminals 1-5. At this time, set "10"
or "11" in Pr. 128.
Item Entry Description
Set 0V as 0% and 5V as 100%.
When "1, 3, 5, 11, 13 or 15" is set in Pr. 73
(5V selected for terminal 2).
Across terminals 2-5
Set 0V as 0% and 10V as 100%.
When "0, 2, 4, 10, 12 or 14" is set in Pr. 73
(10V selected for terminal 2).
