Step 2: Set the traverse range
You can enter up to three traverse ranges.
“Traverse ranges" on page 623. Define the software limit switches as follows:
In the MANUAL operating mode, press the MOD key to select the REF
display. The position displays show the distance to the machine datum
(MP960.x).
With the axis direction buttons or the handwheel, move all axes in positive
and negative direction until they almost reach the emergency stop limit
switches. Write down the displayed positions with algebraic sign.
Enter the noted values in MP91x.x and MP92x.x.
Press the MOD key and select the ACTL display.
Step 3: In MP1391 or MP1392, select the type of control
For control with velocity feedforward:
Enter the temporary input values.
Enter the following test program:
LBL 1
L X <maximum traverse>
R0 FMAX
LX0 FMAX
CALL LBL1 REP 100/100
Display the actual speed (act. speed) with the integrated oscilloscope and,
if necessary, also show the following error (lag).
Start the test program with feed-rate override = 100%.
In MP1090.0 increase the jerk until the overshoot just disappears.
Machine parameters Temporary input value
MP1391 or MP1392 Set to velocity feedforward control
MP1090.0 Enter a very small jerk, e.g. 1
(dependent on the machine)
MP1090.1
MP1092 <greater than rapid traverse>
MP1095 0
MP1096.x 0
MP1099.0 5
MP1099.1 3
MP1396.x 1
MP1521.x 0
