 Changed: 7645.x – Initialization parameter for handwheel at X23 of the
last machine operating panel in the HSCI chain
 New: 7646.x – Reserved for future functions
 New: 7647.x – Reserved for future functions
 New: 7648.x – Reserved for future functions
 New: 7649.x – Initialization parameter for handwheel at X29 of the MC
main computer
 Enhanced: MP7650.x – Counting direction for handwheel
Indices were added to MP7650. MP7650.0 to MP7650.4 are used to
configure the counting direction of the respective handwheel connected.
MP7650.0 for X23 of the last machine operating panel in the HSCI chain, and
MP7650.4 for X29 of the MC.
 Enhanced: MP7680 – Machine parameter with multiple function
Setting bit 18 in MP7680 suppresses the error message "Axis angle not
equal to tilt angle" when a manual probing cycle is used to measure a basic
rotation or to align the workpiece by means of the rotary axis.
This makes it possible to measure the basic rotation using reference marks
that could not be reached without a tilted head. Determining a datum is not
possible, however.
Input:
Bit 18 – Manual measurement of basic rotation with inclined rotary
axes
0 = Error message "Axis angle not equal to tilt angle" is active
1 = Error message is not active
 Enhanced: MP7682 bit 16 – Reserved
Input: 0
 Enhanced: MP7682 bit 17 – Reserved
Input: 0
