6 Error monitoring and error messages
6.1 Error monitoring
The majority of bus module and frequency inverter functions and operating data are continuously monitored
and simultaneously compared with limiting values. If a deviation is detected, the bus module or inverter reacts
with a warning or an error message.
For detailed information, please refer to the relevant main manual of the 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 means of a correspondingly programmed digital input
(SK 200E: (P420) [-…], function {12} or
SK 500E: (P420 ... P425), 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.
Visualisation of the inverter error codes is made via the frequency inverter (see relevant manual).
Errors which are attributable to bus operation are visualised via the bus module. The precise error message is
displayed in parameter P170.
NOTE
The display of a bus error is shown in the operating display of the SimpleBox SK CSX3H by
means of the error group number
E1000. In order to obtain the precise error number, the
module information parameter P170 must be selected. The current error is shown in Array
[01] of this parameter; the last error is stored in Array [02].
The DeviceNet module monitors the following functions:
Cyclic connection to the bus master via the DeviceNet watchdog function (parameterisation is carried out in
the bus master)
Cyclic connection to the bus master and valid control data via the bus module parameter (P151)
