The following options are configurable:
• Signal type
• Pressure sensor Range
• Pressure sensor Type
Setpoint sensor signal types:
Pressure sensor
range (AI2)
1.0 bar
• 0 – 10 V : Voltage range of 0 – 10 V for transfer of setpoint values.
• 2 – 10 V : Voltage range of 2 – 10 V for transfer of setpoint values. If the voltage is below 1
V, the motor is switched off and cable break is detected (see Overview of transfer func-
tions).
• 0 – 20 mA : Electric current range of 0 – 20 mA for transfer of setpoints.
• 4 – 20 mA : Electric current range of 2 – 20 mA for transfer of setpoints. If the current is be-
low 2 mA, the motor is switched off and cable break is detected (see Overview of transfer
functions).
Pressure sensor
type (AI2)
Absolute pressure sensor
Relative pressure sensor
In menu item “Pressure sensor range” the pressure sensor range can be selected.
In menu item “Pressure sensor type” an absolute or a relative pressure sensor type can be se-
lected.
13.4.3 Transfer function Setpoint input and transfer function
Setpoint inputs 0 V .. 10 V / 0 mA .. 20 mA:
For 0 V ... 10 V / 0 mA .. 20 mA the cable break section does not apply.
The setting values for linear section and motor off section are shown on the figure Fig. 25.
In constant speed n-c, setpoint can be set from 30% of maximum speed up to maximum
speed.
For all other control functions, dp-c, PID and pc, setpoint can be set from 0% to 100% of
the sensor range.
