6 Error monitoring and error messages
According to the cause, frequency inverters and technology units generate appropriate messages if they
deviate from their normal operating status.
6.1 PROFINET error monitoring
An error in the frequency inverter (P700) or in the SK TU3-PNT (P170) results in a diagnostic alarm which is
transmitted to the control unit as an "incoming event". The error value is coded as follows:
Error number (P700 or P170) = Alarm number of the diagnostic alarm – 0x100
Example:
During operation, the error E10.3 (P700 Index 1 = 103) = Timeout occurs via the P513 monitoring. The
SK TU3-PNT sends a diagnostic alarm with the value 359 (= 100h + 103 = 256 + 103 = 359) to the control
unit.
With the aid of parameter P163, e.g. during commissioning, various alarms can be sent in order to test the
operation of the control program.
6.2 Error messages in the Bus module SK TU3-PNT
All SK TU3-PNT error messages are displayed in parameter (P170) of the bus module and trigger an error
in the connected FI. This is permanently stored in the FI error statistics. The error messages in the bus
module memory (P170) parameter are lost when the 24V supply voltage is switched off.
6.3 Error messages in the SK 5xxE frequency inverter
Errors cause the frequency inverters to switch off, in order to prevent a device fault.
The following options are available to reset a fault (acknowledge):
1. Switching the mains off and on again,
2. By an appropriately programmed digital input (P420 ... P425 / P470 = Function 12),
3. By switching of the “enable” on the frequency inverter (if no digital input is programmed for
acknowledgement),
4. By Bus acknowledgement or
5. By P506, the automatic error acknowledgement.
The following error messages are directly associated with the Bus module SK TU3-PNT.
FI Error Code Error register
0 No error
10.3 Timeout via P513 monitoring
10.5 General PROFINET configuration error
10.8 The connection between the FI and the SK TU3-PNT had a timeout
