Note Action
Verify that the input to X13/X14 is 24 VDC ±
10%.
• If the measured voltage is normal, pro-
ceed with step
10 .
• If the measured voltage is abnormal,
there is an issue with the 24 VDC supply
from the power unit. See
Troubleshoot-
ing the power unit on page 382 .
Measure the 24_BRAKE input at
connector X13/X14. 2
Make sure that the drive unit is operational. Check the two Link/Activity LEDs
(B & D). These LEDs indicate the
communication status of the mod-
ule. 3
If the Link/Activity LED is:
• Yellow, steady: The communication link
is established. The drive unit may be
faulty, see
Replacing the drive unit on
page 263 .
• Flashing yellow: The communication link
is established and data is transferred
through the port. The drive unit may be
faulty, see
Replacing the drive unit on
page 263 .
• Off: The EtherCAT link is not established.
Proceed with step
5 .
If the connection and cable seem OK, proceed
with step
6 .
Check the connectors at T4.X1 (24V
SYS DRV IN) and T4.X2 (24V SYS
DRV OUT). Make sure that the
power cables are connected prop-
erly at both ends. 4
If there is a problem with the connection, pro-
ceed with step
7 .
If the connection seems OK, proceed with step
6 .
Check the EtherCAT cables
X3/X4/X16/X18. Make sure that the
cables are connected properly at
both ends. 5
If there is a problem with the connection, pro-
ceed with step
7 .
Verify that the input to X1/X2 is 24 VDC ± 10%.
• If the measured voltage is normal, re-
place the drive unit. See
Replacing the
drive unit on page 263 .
• If the measured voltage is abnormal,
there is an issue with the 24 VDC supply
from the power unit. See
Troubleshoot-
ing the power unit on page 382 .
Measure the 24VDC SYS DRV input
at connector X1/X2. 6
Make sure that the power cable is connected
properly at both ends.
• If the Module Status LED is green, the
fault has been fixed. Proceed with step
1 .
• If the Module Status LED is off, the fault
remains. Proceed with step
6 .
Restore the power connection
between the drive unit and the
power unit by reconnecting the
power cable. 7
Make sure the EtherCAT cables are connected
properly on both ends.
• If the Link/Activity LED is yellow, the fault
has been fixed. Proceed with step
1 .
• If the Link/Activity LED is off, the fault
remains. Replace the EtherCAT cables,
see
9 .
Restore the communication
between the modules by reconnect-
ing the EtherCAT cables. 8
• If the Link/Activity LED is yellow, the fault
has been fixed. Proceed with step
1 .
• If the Link/Activity LED is off, the fault
remains. Replace the drive unit, see
Re-
placing the drive unit on page 263 .
Replace the EtherCAT cables. 9
