(P1.3)
P9.6 334 — PID controller, process variable (PV) source
(Actual value or feedback)
2
0 Fieldbus
1 AI1 and S2, (see figure on Page 39)
P2.1 = 0 (0 mA/0V)
P2.1 = 1 (4 mA/2V)
2 AI2 and S3, (see figure on Page 39)
P2.5 = 0 (0 mA/0V)
P2.5 = 1 (4 mA/2V)
P9.7 336 — PID controller, actual value limiting, minimum 0.0
0–100% —
P9.8 337 — PID controller, actual value limiting, maximum 100.0
0–100% —
P9.9 340 — PID controller, controller deviation 0
0 Not inverted
1 Inverted
Inverted PID control (P9.9 = 1) is used in applications in which
the feedback value generator supplies an inverted signal
Example: With increasing pressure, a pressure sensor output
signal (+10V…0V = 0…max. bar) drops
P9.10 132 — PID controller, D rate time 0.00
0–10s Differential time constant
P9.11 1431 — PID controller, output filter, delay time 0.0
0.00–10.00s —
P9.12 1016 — Sleep mode, frequency 0.00
0–P6.4 Hz The frequency inverter stops automatically if the frequency of
the drive drops below the sleep level defined by this parameter
for a longer period than the time defined by parameter P9.14
P9.13 1018 — Sleep mode, wake up setpoint 25.0
0.00–100% The wake up setpoint defines the value which the PID controller
process value (P9.6) must drop below before a RUN mode of
the frequency inverter is restored.
P9.14 1017 — Sleep mode, delay time 30
0–3600s This parameter determines the minimum period in which the
frequency inverter must stay below the frequency set at P9.12
before the frequency inverter is stopped
