Hardware error
If one of the following errors occurs, the load is de-energized and bit
byte.
• Open load / broken wire (OpenLoad,
• Failure of the 24 V control supply (NoControlPower,
)
(The terminal is automatically reinitialized when the control voltage returns)
If an error occurs, it first has to be rectified and subsequently acknowledged and thus cancelled by setting bit
Dithering
Feature bit
must be set to activate the dither.
The purpose of this function is to eliminate magnetization effects. Dithering involves modulating a
rectangular signal on top of the actual output value. The configuration required for this depends a lot on the
particular application. It must be determined with the aid of the characteristic data of whatever actuator is
connected.
The following parameters can be set:
Name
Register Value range
Description
Frequency - f
10 Hz to 500 Hz The frequency of the rectangular signal; the resolution of the
setting is 1 Hz.
Amplitude - i
0% to 100%
The amplitude of the rectangular signal; the resolution is 1%
(with reference to the output current that has been set in

Switch-off ramp -
t
0 ms to
32767 ms
When switched on, the dither signal jumps immediately to the
amplitude set in R38. When switched off, the signal is
attenuated linearly over the time configured here; the
resolution is 1 ms.
