RUN Value/Range Description
P9.15 1433 — Hysteresis, upper limit 0.0
0.00–100% The FBV (Feedback Value Check) message P5.1 (2.3) = 25 is
output if the actual value in RUN mode is below the lower limit
value P9.16. It stays active until:
The actual value exceeds the upper limit value P = 9.15
The frequency inverter switches from RUN mode to STOP mode
P9.16 1434 — Hysteresis, lower limit 0.0
0.00–100% See P9.15
P9.17 1435 — PID controller, max. controller deviation 3.0
0.00–100% If the PID controller is activated (P9.1 = 1), and the deviation
between the setpoint and the actual value exceeds the value
entered here, the PID monitoring is activated. Setting at P5.1
(2.3) = 12
P9.18 1475 — PID controller, reference value scaling 1
0.1–32.7 Setpoint display, multiplication of a factor to display
process-adjusted variables
The value is displayed in M1.17
P9.19 1476 — PID controller, process value scaling 1
0.1–32.7 Actual value indication, multiplication factor for displaying
process variables
The value is displayed in M1.18
P9.20 1478 — PID controller, output signal limit 100.0
