6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.7 Axis-specific MD 2 (axial data 2)
1116*
Default value
1
MD 1116* is used to set the multiplication factor for the actual position pulses when using the
6FX 1145-6B... HMS measuring-circuit module. On Power On, the NC software checks to see
whether an HMS measuring-circuit module has been inserted; only when this is the case does
MD 1116* take effect.
The following multiplication factors can be specified:
Measuring system resolution = measuring system x 4 x MD 1116*
Note
This MD also has an effect when the measuring system of the digital drive (611-D) is used.
1124*
Default value
0
Active:
MD 1124* is used to modify the setpoint speed in proportion to acceleration. Where position
control cycles are < 1 ms, the rise process can be accelerated even more by the D
component. It should not be used with larger sampling intervals.
Note:
As from SW 4, for 8 parameter blocks
1140 *
Default value
0
This MD has the same meaning as MD 312*, see also functional description of parameter set
switchover.
