12.27.5 Operator inputs

12.27.5
The operator inputs the machine data for the parameter sets under DIAGNOSIS/START-
UP/MACHINE DATA/NCK-MACHINE DATA/AXIS or SPINDLE where the new MD are arranged
under the existing parameter set data.
12.27.6
During control power-up, the values from the 1st parameter set remain active until the PLC
interface has been supplied with valid values.
Subsequent inputs of parameter sets are unaffected by channel reset, mode group reset and
restart operations.
NCK power ON/OFF invalidates these settings, the values of the 1st parameter set are
activated again.
The selected parameter set number for the parameter group "Drive" remains valid even when
the digital drive is switched off, i.e. when the drive is switched on again, it receives the same,
cyclically transmitted PaSNo.
12.27.7
If the "Extended parameter set switchover" function is not activated in MD 1828*, bit 0 (axis)
or MD 523*, bit 0 (spindle), then the old functionality (prior to SW 4) regarding traversing limits,
tapping, gear stage switchover and drives parameters is applicable. The associated MD of the
extended parameter sets are not activated.
The following boundary conditions apply when this function is activated:
Spindle:
Software version 4 is compatible with previous versions in terms of spindle gear stage
switchover functionality. Parameters which could not be switched over with SW versions up to
and including SW 3 must be set to the appropriate value of the first parameter set when SW
version 4 is installed.
Axis:
The operating principle of the "Tapping without compensating chuck" function is compatible to
that applied in SW 3. Parameters in the 2nd set of parameter group "Position control" which
cannot be switched over with SW version 3 must be set to the same values as those in the 1st
set of this parameter group.
Drive:
If a drive is assigned more than once, then the parameter set number of the currently active
axis/spindle, which also supplies the setpoint, is valid in each case. The current parameter set
remains valid provided no controller enabling command is applied.
