Fault
Message/Warning
Cause
Remedy
F101
Firmware type mismatch.
Installed firmware is not compatible
with the drive hardware.
Load compatible firmware into
drive.
n101
The FPGA is a lab FPGA.
The FPGA is a lab version FPGA.
Load the released FPGA ver
-
sion that is compatible with the
operational firmware.
F102
Resident firmware failed.
Software failure detected.
Restart drive. If issue persists,
contact technical support.
n102
Operational FPGA is not a
default FPGA.
The FPGA minor version is larger than
the operational firmware default FPGA
minor version.
Load the released FPGA ver
-
sion that is compatible with the
operational firmware.
F103
Resident FPGA failed.
Software failure detected. Load resi-
dent FPGA failure occurred (several
cases according to flow-chart, includ
-
ing compatible image to FPGA type
and fieldbus type)
Restart drive. If issue persists,
contact technical support.
F104
Operational FPga failed.
Software failure detected. Load opera-
tional FPGA failure occurred (several
cases according to flowchart).
Restart drive. If issue persists,
contact technical support.
F105
volatile memory stamp
invalid.
Non-volatile memory stamp is cor-
rupted or invalid.
Reset the drive to default
memory values.
F106
Non- volatile memory data. Non-volatile memory data is corrupted
or invalid. When this fault occurs after
a firmware download, it is not an indi
-
cation of a problem (clear the fault and
perform a "save" to the drive).
Reset the drive to default
memory values.
n107
Positive switch limit.
Positive software position limit is
exceeded.
Move the load away from the
limits.
n108
Negative switch limit.
Negative software position limit is
exceeded.
Move the load away from the
limits.
F121
Homing error.
Drive did not finish homing sequence.
Check homing sensor, homing
mode, and homing configura
-
tion.
F123
n123
Invalid motion task.
Invalid motion task.
Check motion tasks settings and
parameters to make sure that
the values entered will produce
a valid motion task.
F125
n125
Synchronization lost.
The fieldbus lost synchronization.
Check fieldbus connection (X5
and X6 if you are using Ether
-
CAT; X12 and X13 if you are
using CANopen) or the settings
of your WtherCAT or CANopen-
master.
F126
n126
Too much movement.
Too much movement wa created dur-
ing a Bode plot. Motor is unstable and
is not following drive instructions.
Check that the system is closed
loop stable. Refer to the system
tuning guide.
