NC drive number
The motor measuring system has a
motor encoder with voltage output.
This calls for an IPU submodule
with voltage input. A submodule
other than that expected has been
detected.
Replace servo control module.
Check plug-on connections, take
measures to eliminate noise (scree-
ning, check ground connections).
FDD / MSD
F024 xx / xx In executing the software, an illegal
internal axis number has been
found. Possible causes: Defective
servo control module, electroma-
gnetic compatibility faults.
Replace servo control module. Take
measures to eliminate noise (scree-
ning, check ground connections).
FDD / MSD
F025 xx / xx In executing the software, an illegal
internal physical axis number has
been found. Possible causes: De-
fective servo control module, elec-
tromagnetic compatibility faults.
Replace servo control module. Take
measures to eliminate noise (scree-
ning, check ground connections).
FDD / MSD
F026 xx / Axis No. The NC attempts to log on an FDD
module as MSD. There are possibly
faults in the communication via the
drive bus or servo control module is
defective.
Replace servo control module.
Check plug-on connections, take
measures to eliminate noise (scree-
ning, check ground connections).
FDD
F027 xx / Axis No. The NC attempts to log on an MSD
module as FDD. There are possibly
faults in the communication via the
drive bus or servo control module is
defective.
Replace servo control module.
Check plug-on connections, take
measures to eliminate noise (scree-
ning, check ground connections).

F028 xx / Axis No.

ter of the rele-
vant PCU ASIC
NC drive number
For the direct measuring system,
only certain submodules are allo-
wed. A submodule has been detec-
ted that is not allowed.
Replace servo control module.
Check plug-on connections, take
measures to eliminate noise (scree-
ning, check ground connections).
FDD / MSD
F031 Error code / Axis
No.
0x40; illegal
PDU length
0x41; axes do
not have the
same PDU
length
0x42; PDU
length not a
word multiple
0x43; axes do
not have the
same NC type
The NC has not transferred permis-
sible corner data to the drive for
communication via the drive bus.
This is presumably caused by faults
on the drive bus or a defective
servo control module.
Replace servo control module.
Check plug-on connections, take
measures to eliminate noise (scree-
ning, check ground connections).
FDD / MSD
F033 Error code / xx
0x51; wrong
data format in
element list
0x52; wrong
conversion
group specified
in Refresh
The drive software is no longer con-
sistent. This is presumably caused
by a hardware fault on the servo
control module.
Reload drive software
Replace servo control module.

Error numbers
have different
load sequences
Error code / in-
correct address
0 or incorrect
address
0x60; incorrect
response of
SERVO on STF
handshake
0x61; error dur-
ing RAM check
0x62; transport
checksum does
not correspond
to that of
SERVO
Errors have been found on loading
the drive software. This is caused
either by errors in transmission on
the drive bus or a defective servo
control module.
Check drive bus cable and connec-
tors, take measures to eliminate
noise (screening, check ground
connections), replace servo control
module.
