The tuning of the resolver is
disturbed(motor failure).

N° Check
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.
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.
24 Please contact your local Customer Center.
25 Check that the contacts of the motor
connector or of the cable are neither twisted
nor pushed back.

torque ripple of the "torque versus time"
curve saved in the unit.
If so, please contact your local Customer
Center
28 Please contact your local Customer Center.
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.
32 Check the presence of tightening cycles.
Check that the selected cycle is programmed
correctly.
33 Refer to No. 18.
