Operating Instructions ACU
Abs. value of calculated pressure
0.0 kPa ... Nominal Pressure 398.
Operation modes in analog operation with signs.
16.2.1.1 Output Characteristic
The voltage range of the output signal at multifunction output 1 can be adjusted. The value range of
the actual value selected via parameter Analog Operation 553 is assigned to the value range of the
output signal which is adjusted via the parameters Voltage 100% 551 and Voltage 0% 552.
Analog Operation 553 with abs. actual
value:
Analog Operation 553 with sign:
With parameters Voltage 100% 551 and Voltage 0% 552 the voltage range at 100% and 0% of
the output parameter is set. If the output value exceeds the reference value, the output voltage also
exceeds the value of the parameter Voltage 100% 551 up to the maximum value of 24 V.
16.2.2 Frequency Output MFO1F
Multifunction output MFO1 can be used as a frequency output by setting parameter Operation
Mode 550 = “3 - Repetition Frequency”. The DC 24 V output signal is assigned to the absolute
speed/frequency value via parameter Repetition Freq. Operation 555. The selection of the
operation modes depends on the extension modules installed as an option.
