Description
Measure
Acknowledgement
1:CAN LifeGuard
The device detects the
Life-Guarding
event
(master no longer sends any
Remote Transmit Request).
Check the CANOpen master.
Switch off/on the Esc key of the
device at the front of the inverter
or rising flank of the enable
signal or programmed
acknowledgement
2:CAN Sync Error
Sync message was not received within
the timeout period that is calculated
from the
A201 Cycle Period Timeout
as
follows:
•
A201
≤
20 ms:
Timeout period =
A201
* 4,
•
20 ms <
A201
≤
200 ms:
Timeout period =
A201
* 3,
•
Otherwise: Timeout period =
A201
*
2
•
Make sure that the
A201
parameter
is correctly set.
•
Make sure that the master sends
the sync message reliably.
Switch off/on the Esc key of the
device at the front of the inverter
or rising flank of the enable
signal or programmed
acknowledgement
3:CAN Bus Off
The CAN controller in the inverter has
switched off due to critical and repeated
CAN bit timing errors. The CAN
controller is restarted after a waiting
time of 2 s and acknowledgement of the
malfunction.
•
Make sure that the CAN baud rate
was correctly set.
•
Check the wiring.
•
Check the bit timing of a different
CAN subscriber.
Switch off/on the Esc key of the
device at the front of the inverter
or rising flank of the enable
signal or programmed
acknowledgement
4:PZD-Timeout
•
Failure of the cyclic data connection
(PROFIBUS master no longer
sends) or connection is faulty or
•
PROFINET IO controller no longer
sends or the connection is faulty
•
Check the PLC (RUN switch, set
cycle time).
•
Check the wiring.
Switch off/on the Esc key of the
device at the front of the inverter
or rising flank of the enable
signal or programmed
acknowledgement
