16.3.5 Fixing the software limit switch ranges
Determine the software limit switch ranges (see section "Machine axes") as follows:
In "Manual operation" mode select the REF-
display with the MOD key.
↓
Position-displays show the distance to the
machine datum .
↓
Move all axes with the aid of the direction keys or
the handwheel in positive and negative direction to
just before the EMERGENCY STOP limit switches. Note the
values in the positional-displays and their sign.
↓
Enter the noted values in MP910 or MP920.
↓
Select actual-value display with MOD key.
16.3.6 Optimizing the control with lag (MP1390 = 1)
The following provisional values can be entered for the machine parameters which determine the
control characteristics:
Machine parameter Function provisional entry value
MP1050 Analogue voltage for rapid
traverse 9 V
MP1060 Acceleration As measured on the machine
(see "Preparation of the machine")
MP1810 kv factor 1
MP1820 Multiplication factor 1
MP1830 Kink point
Entry value =
max. mach. speed
Rapid traverse
· % 100
These values can usually be further optimized.
