Possible Cause Solution Fault Type
continued E16.22 CANlink station
numbers conflict.
Change the same CAN station numbers to
different ones by using FD‑13 (CAN station
No.).
Axis fault
E16.52 The EtherCAT
communication card
has a EEPROM fault.
1. If the programming or upgrading of the
communication card fails, program the
communication card again.
2. If this fault occurs during normal use,
replace the communication card.
Axis fault
E16.53 The slave control chip of
the EtherCAT
communication card is
faulty.
1. If the programming or upgrading of the
communication card fails, program the
communication card again.
2. If this fault occurs during normal use,
replace the communication card.
Axis fault
E16.55 The EtherCAT
parameters are set
incorrectly.
When the master station goes wrong, check
whether it sends synchronous frame (FD‑78).
If not, make sure that TPDO and RPDO have
been configured for the master PDO. If the
master PDO is configured correctly, check
the network port status (FD‑72 to FD‑77) and
make sure that the communication cable is
connected properly.
Axis fault
E16.71 The master station is
offline when the
communication card is
operating.
Check whether the connection between the
communication card and PLC is in poor
contact. Make sure a proper connection.
Axis fault
E16.72 The internal slave
station is offline when
the communication card
is operating.
Check whether the connection between the
communication card and power supply unit
is in poor contact. Make sure a proper
connection.
Axis fault
E16.74 The communication
card configuration goes
wrong.
Check whether the configured slave station
exists and whether startup with station lost
is disabled (FD‑50 of the power supply unit =
0).
Axis fault
E16.75 Configuring the drive
unit mapping by the
communication card
goes wrong.
Check the process data and the number of
mapping relations configured for the drive
unit, and make sure that they are consistent.
Axis fault
E16.76 Configuring the power
supply unit mapping by
the communication card
goes wrong.
Check the process data and the number of
mapping relations configured for the power
supply unit, and make sure that they are
consistent.
