Parameter $TC_TPG2 must therefore be assigned as follows:
Binary: $TC_TPG2[1]= 'B111 0000 0011 1000 0001 1101'
(Bit 22 ... Bit 0)
Hexadecimal: $TC_TPG2[1]= 'H70381D'
Decimal: $TC_TPG2[1]='D7354397'
Note
If the chaining specification is subsequently altered, the values of the two cutting edges are
not automatically adjusted, but only after one parameter has been altered.
Minimum wheel radius and width $TC_TPG3 $TC_TPG4
The limit values for the grinding wheel radius and width must be entered in these
parameters. These parameter values are used to monitor the grinding wheel geometry.
Note
It must be noted that the minimum grinding wheel radius must be specified in the Cartesian
coordinate system for an inclined grinding wheel. A signal is output at the PLC interface if the
grinding wheel width and radius drop below the minimum limits. Users can use these signals
to define their error strategy.
Current width $TC_TPG5
The width of the grinding wheel measured, for example, after the dressing operation, is
entered here.
Maximum speed and grinding wheel peripheral speed $TC_TPG6 $TC_TPG7
The upper limit values for maximum speed and peripheral speed of the grinding wheel must
be entered in these parameters.
Precondition: A spindle has been declared.
