Product overview
Hardware error
If one of the following errors occurs, the load is de-energized and bit SB1.6 [} 40] (Error) is set in the Status
byte.
• UnderVoltage R0.11 [} 43]
• OverCurrent, R0.12 [} 43]
• Open load / broken wire (OpenLoad, R0.13 [} 43])
• Failure of the 24 V control supply (NoControlPower, R0.14 [} 43])
(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
CB1.6 [} 40] in the control byte.
Dithering
Feature bit R32.5 [} 45] and control bit CB1.0 [} 40] 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:

Description
10 Hz to 500 Hz The frequency of the rectangular signal; the resolution of the
setting is 1 Hz.
0% to 100% The amplitude of the rectangular signal; the resolution is 1%
(with reference to the output current that has been set in
register R36 [} 45])
0 ms to When switched on, the dither signal jumps immediately to the
32767 ms amplitude set in R38. When switched off, the signal is
attenuated linearly over the time configured here; the
resolution is 1 ms.
