13
4:PZD-Timeout • Failure of the cyclic data connec-
tion (PROFIBUS master no lon-
ger sends) or connection is faulty
or
• PROFINET IO controller no lon-
ger 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 in-
verter or rising flank of the en-
able signal or programmed
acknowledgement
5:USS Failure of cyclic data connection
(USS).
Check the USS master. Switch off/on the Esc key of
the device at the front of the in-
verter or rising flank of the en-
able signal or programmed
acknowledgement
6:EtherCAT PDO-Ti The inverter did not receive process
data in the time period that was pa-
rameterized in A258.
• Make sure that the A252.x,
A253.x, A256, A257.x, A258,
A259.x, A260, A261.x, A262.x,
A263.x, A264.x, A265.x, A266
and A267.x parameters are cor-
rectly set.
• Make sure that the timeout value
parameterized in A258 matches
the A150 cycle time (of the in-
verter) and the cycle time of the
controller or EtherCAT masters
that were selected.
• Check the wiring
• Check the EtherCat state of the
inverter and the controller or Eth-
erCAT master.
• Check whether CoE emergency
messages are present in the con-
troller or the EtherCAT master.
Switch the device off/on or
programmed acknowledge-
ment. Note that an action must
also occur in the controller or
the EtherCAT master for com-
plete acknowledgement.
