1033 ACTUAL VALUE SPECIAL DISPLAY MINIMUM 57 (2.2.46, 2.9.29)
1034 ACTUAL VALUE SPECIAL DISPLAY MAXIMUM 57 (2.2.47, 2.9.30)
1035 ACTUAL VALUE SPECIAL DISPLAY DECIMALS 57 (2.2.48, 2.9.31)
1036 ACTUAL VALUE SPECIAL DISPLAY UNIT 57 (2.2.49, 2.9.32)
The Actual value special display parameters are used to convert and display the actual value
signal in a form more informative to the user.
The Actual value special display parameters are available in PID Control Application and
Pump and Fan Control Application.
EXAMPLE:
The actual value signal sent from a sensor (in mA) tells you the amount of waste water
pumped from a tank per second. The signal range is 0(4)-20 mA. Instead of receiving the
level of the actual value signal (in mA) on the display, you wish to receive the amount of water
pumped in m3/s. You then set a value for parameter ID1033 to correspond to the minimum
signal level (0/4 mA) and another value for parameter ID1034 to correspond to the maximum
signal level (20 mA). The number of decimals needed can be set with parameter ID1035 and

The AC drive receives no interlock feedback from the drives
The AC drive receives interlock feedback from the drives. In
case one of the drives is, for some reason, disconnected
from the system and eventually reconnected, it will be placed
last in the autochange line without stopping the system.
However, if the autochange order now becomes, for exam-
ple, [P1 -> P3 -> P4 -> P2], it will be updated in the next Stop
(autochange, sleep, stop, etc.)
EXAMPLE:
[P1-> P3 -> P4] -> [P2 LOCKED] -> [P1 -> P3 -> P4 -> P2] ->
[SLEEP] -> [P1 -> P2 -> P3 -> P4]
The AC drive receives interlock feedback from the drives. At
reconnection of a drive to the autochange line, the automat-
ics will stop all motors immediately and re-start with a new
set-up.
EXAMPLE:
[P1 -> P2 -> P4] -> [P3 LOCKED] -> [STOP] -> [P1 -> P2 -> P3
-> P4]
