9.5.4.3 Power ON/OFF – monitoring functions – special functions (SW 4)
Power ON procedure After power ON, the boot file stored for the neuronal QEC must be transferred
from the MMC to the SERVO. These data are transferred in the same way as
611D drive machine data are booted.
Service number 328 is output if bit 0 in NC-MD 18120 is set at the instant of
power ON for an axis which does not have an axial boot file.
Please note that no compensation is applied to the axis concerned in this case.
This alarm is output on Power ON only if the neuronal QEC is activated via bit 0
in NC-MD 18120 at that instant.
Incorrect As with the previous software version, service number 328 is output in
parameterization response to incorrect/illegal parameter settings caused by changes to
of machine data machine data. Possible causes for this error message are:
S Activation of neuronal QEC (NC-MD 18120, bit 0) without valid parameter set-
tings for function parameters. This parameterization error is also indicated on
power ON if the start-up results have not been saved in the boot file.
S Activation of neuronal QEC (NC-MD 18120, bit 0) with learning rate setting of
0 or learning rate parameterized as 0 (NC-MD 13680) when neuronal QEC is
active.
S Activation of neuronal QEC (NC-MD 18120, bit 0) with error measuring time
tM2 set to 0 or error measuring time tM2 parameterized to 0 (NC-MD 13760)
when neuronal QEC is active.
S Previously detected incorrect/illegal QEC parameter settings when the neuro-
nal QEC is not activated.
Incorrect Incorrect inputs for the function parameter settings trigger a start-up application
parameter iinputs error message. Possible causes and remedies can be found under section
for start-up function headings “Neuronal QEC parameterization” and “Alarm description”.
