Troubleshooting procedure
The troubleshooting table is supposed to be used as a detailed instruction together
with the troubleshooting flowchart.
Tip
In setups with several additional drive units:
•
Measure voltage on the last unit in the chain first, and then work your way
backwards.
•
Check if the FlexPendant indicates which unit is faulty. If not, replace one
unit at a time.
Note
Action
Make sure that the additional drive unit is oper-
ational.
Power on the controller. Check the
Module Status LED (A) on the addi-
tional drive unit.
1
Wait at least 1 min after power-on.
If the Module Status LED is:
•
Off: The additional drive unit is in the
power off state. Proceed with step
•
Flashing red (~ 1Hz): Firmware error or
self-test failure.
Upgrade the firmware. If the problem
persists, the additional drive unit may be
faulty, see
Replacing the additional drive
•
Flashing green (~ 1Hz): Communication
error to another module. Proceed with
step
.
Verify that the input to X13/X14 is 24 VDC ±
10%.
•
If the measured voltage is normal, pro-
ceed with step
.
•
If the measured voltage is abnormal,
proceed with step
.
Measure the 24V_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 additional drive
•
Flashing yellow: The communication link
is established and data is transferred
through the port. Proceed with step
.
•
Off: The EtherCAT link is not established.
Proceed with step
.
If the connection and cable seem OK, proceed
with step
Check the connectors at T41.X1
(24V SYS DRV IN) and T41.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
If the connection seems OK, proceed with step
.
Check the EtherCAT/SMB cables
X3/X4/X16/X18. Make sure that the
cables are connected properly at
both ends.

If there is a problem with the connection, pro-
ceed with step
