Resetting synchronism correction
Versions
Synchronism correction can be reset in the following ways:
•
Writing value "0" to variable $AA_COUP_CORR[S<n>].
Synchronism correction is suppressed via a ramp with reduced accelerating power (just as
when a correction value is implemented).
• Resetting synchronism correction via the PLC.
On the rising edge of the NC/PLC interface signal:
DB31, ... DBX31.7 (reset synchronism correction),
the variable $AA_COUP_CORR[S<n>] is set to zero and synchronism correction is reset
as follows:
-
existing synchronism correction is then transferred to the setpoint position.
-
Requirements
A requirement for resetting synchronism correction is that the correction value is not currently
being calculated (see "Measuring the deviation from synchronism [Page 328]").
End of the reset procedure
When the reset procedure is complete, the following NC/PLC interface signal is set:
DB31, ... DBX99.2 (synchronism correction implemented)
If the NC/PLC interface signal DB31, ... DBX103.0 (synchronism correction is taken into
account) is also reset, so too can the NC/PLC interface signal DB31, ... DBX31.7 (reset
synchronism correction) be reset.
332
If the spindle is in speed control mode, the correction movement is stopped. The
In all other cases, the synchronism correction that has already been implemented is
reset in exactly the same way as when variable $AA_COUP_CORR[S<n>] is set to
zero.
