3.6.2 Response to malfunction messages
3.6.2.1 Selection of the response
Abnormal stopping (i.e., automatic shutdown of the drive) is possible for all errors that do not enforce immediate
shutdown of the modulation or for which pre-warnings can be generated.
If abnormal stopping is reasonable in the application, the possibility to set a digital output is available for many
malfunctions.
The response is programmable for the following malfunctions:
- Ext. error Pn.03 Reaction to external fault
- Watchdog Pn.05 Watchdog reaction
- Set selection error Pn.18 E.Set stopping mode
Other errors switch off the modulation, but a pre-warnings can be generated prior to their triggering. In the
time between the pre-warning signal and the triggering of the error, the drive can be stopped. The response is
programmable:
- Overload Pn.08 warning OL stop. mode
- Heat sink overtemperature Pn.10 Heat sink overtemperature response
- internal overtemperature Pn.16 Internal overtemperature response
The descriptions of the errors and the corresponding pre-warning signals are contained in chapter 5.1 "Error
assistance".
