8.3 Timeout control
After first data exchange via the PLC Port #17220, a timeout check will be activated. If no data is
exchanged for more than 10 seconds, the frequency will respond in the way set in parameter
Bus
Error Behaviour
388. and switch to fault status with error message F2714 “Communication Loss to
PLC”.
Bus Error Behaviour
388 Function
0 - no response Operating point is maintained.
1 - Error “Fault” status will be activated immediately. Factory setting.
2 - Stop
Control command “Disable voltage” and switch to “switch on disa-
bled” status.
3 - Quick stop
Control command “Quick stop” and switch to “switch on disabled”
status.
4 - Sh Error
Control command “Disable operation” and switch to “Error” status
once the drive has been shut down.
5 - Quick stop + Error
Control command “Quick stop” and switch to “Error” status once
the drive has been shut down.
The parameter settings
Bus Error Behaviour
388 = 2…5 are evaluated depending on
parameter
Local/Remote
412.
For evaluation of settings 2…5, parameter
Local/Remote
412 must be set to value “1 -
Control via statemachine”.
8.4 Resetting errors
Depending on the settings and operating state of the device, errors can be reset in different ways:
• In controller via Parameter
Local/Remote
412 = 1 - Statemachine:
Set bit 7
Control word
410 = 0x8000.
•
By pressing the stop button of the control panel:
Resetting by pressing the STOP button is only possible if Parameter
Local/Remote
412 permits
control via the control panel.
• Via parameter
Error acknowledgment
103 which is assigned a logic signal or a digital input
A reset via a digital signal can only be carried out when parameter
Local/Remote
412 permits this
or when an input with the addition (hardware) is selected in the case of physical inputs.
Some errors will occur again after an error reset. In such cases, it may be necessary to
take certain measures (e.g. moving from a limit switch in the non-disabled direction).
