Symptoms
Possible causes
N° Check
The tool does not always start. Faulty contact in the trigger
switch.
21
In the "Maintenance - Inputs/Outputs" menu,
check the switching of the concerned input.
If there is a fault, please contact your local
customer center.
Seen from the controller side,
the tool does not reach the
programmed torque or hardly
reaches it.
The motor overheats.
The tool is stopped by the
"maximum current" instruction.
The angle-head efficiency has
deteriorated to a large extent.
23
If the wear of the angle head is low, a
dynamic calibration could compensate the
drift.
If not, please contact your local Customer
Center for a maintenance.
The "memory" board is faulty.
24
Please contact your local Customer Center.
Motor issue caused either by
● Damaged stator (motor
failure).
● Faulty cable
● Faulty servo-driver.
25
Check that the contacts of the motor
connector or of the cable are neither twisted
nor pushed back.
Replace the servo driver.
If the problem is not solved, please contact
your local customer center.
The tuning of the resolver is
disturbed(motor failure)
26
No check is possible. Rule out every other
possible cause.
Please contact your local customer center
for maintenance.
Dispersion or abnormal
deviation in the tightening
results.
The angle head is faulty.
27
This can be confirmed by checking the
torque ripple of the "torque versus time"
curve saved in the unit.
If so, please contact your local Customer
Center
Transducer or internal
connections damaged.
28
Please contact your local Customer Center.
The tool does not run in run
reverse mode.
The Tightening / Untightening
reversing gearbox is faulty.
The run reverse speed is set
to 0.
30
In the "Tests, Inputs/outputs" menu, check
the switching of bit 7 when the reversing
gearbox is activated.
Check the "Spindle validation on run reverse"
parameter.
Test commutation between pins 2 and 5 of
the tool connector.
Check the value of the run reverse speed
in the "Parameters/Station" menu. If the
reversing gearbox is running correctly, the
tool LEDs should blink.
The tool does not run in
tightening mode, but runs in
run reverse mode.
Loss of controller memory.
32
Check the presence of tightening cycles.
Check that the selected cycle is programmed
correctly.
Transducer fault.
33
Refer to No. 18.
The Tightening / Untightening
reversing gearbox is stuck in
