Fig. 25: Setpoint input 0 – 10V or 0 – 20mA
If analog signal is smaller than 0.9 V or 1.8 mA, the motor is switched off. The cable break
detection is not active. With an analog signal between 2 V and 10 V or between 4 mA and
20 mA, signal is interpolated linearly. The applied analog signal of 0.9 ... 2 V or 1.8 ... 4 mA
represents the setpoint at "0 %" or minimum speed. The analog signal of 10 V or 20 mA
represents the setpoint at "100 %" or maximum speed.
Setpoint inputs 2V .. 10 V / 4 mA .. 20 mA:
The setting values for linear section, motor off section and cable break section are shown
on the figure Fig. 26.
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, dp-v, PID and pc, setpoint can be set from 0% to
100% of the sensor range.

Setpoint

Fig. 26: Setpoint Input 2 - 10V or 4-20mA
An analog signal smaller than 1 V or 2 mA is detected as a cable break. In this case a substi-
tute setpoint takes effect. The substitute setpoint is set in the menu "Control setting".
With an analog signal between 1 V and 2.8 V or between 2 mA and 5.6 mA, the motor is
switched off. With an analog signal between 5 V and 10 V or between 10 mA and 20 mA,
signal is interpolated linearly. The applied analog signal of 2.8 ... 5 V or 5.6 ...10 mA repres-
ents the setpoint at "0 %" or minimum speed. The analog signal of 10 V or 20 mA repres-
ents the setpoint at "100 %" or maximum speed.
Sensor input and transfer function
Sensor inputs 0 V .. 10 V / 0 mA .. 20 mA:
For 0 V ... 10 V / 0 mA .. 20 mA only linear section is applied.
The setting values for linear section is shown on the figure Fig.27.
