9.5.1 General
9.5.1.1 Error Message (indication by „Error occurred”)
Errors which are indicated in the Bit (Error occurred) like for example „Over Current” or „Cable Fraction” can be reset with
the following action :
- Set input signal for the hardware enable at the according module at terminal X3/1 (9) to „Low” and then go back to „High”
- Setting and resetting of the Bits (0x80) Bus-Disable
Mandatory condition for resetting an error is that the failure causing the error has been cleared or removed.
Error numbers:
The corresponding error numbers can be found in the respective manual of the DAC-4x(A).
Generally, the following error table is valid:

Table 10: Error numbers
If parameter E 23 has a value not equal to 0 (Profinet timeout is activated). Depending on parameter E 26, there are
different responses from the device.
• E 26 = off (0)
The device reacts with a blinking enable LED about to long time between valid Profinet telegrams. Those
versions continue with work if a new valid telegram is detected. No separate acknowledges with the enable
signal is needed.
• E 26 = 1
The device reacts with a shining Error LED about to long time between valid Profinet telegrams. Those versions
do not continue with work if a new valid telegram is detected. A separate acknowledge with the enable signal is
needed.
Generally, the electronic discards every set point in error case and the outputs will be disabled.
9.5.1.2 Explanation for „Hardware Enable” and „Software Disable”:
Generally speaking, the hardware enable must be present („high” level) in order to get a signal (current) at the output
stages. Besides the hardware enable a software disable can be used in order to „override” the hardware enable. So even
if the hardware signal is present, with the according software command the module can be disabled!
This means that the hardware enable can be hardwired and the software disable can be used in order to drop the output
signal to zero or also in order to quit errors.
