PI E-871.1A1N, User Manual, Page: 59 / 226

✓
If PI provided a custom positioner database for your positioner, the dataset was imported
into PIStages3 (p. 47) .
✓
You have installed the positioner in the same way as it will be used in your application
(corresponding load, orientation, and mounting).
✓
You have connected the positioner to the E-871.1A1N (p. 46) .
✓
You have established communication between the E-871.1A1N and the PC with
PIMikroMove (p. 53) .
NOTICE
Damage due to disabled limit switch evaluation!
The collision of a moving part at the end of the travel range, or with an obstacle, as well as
high accelerations, can cause damage to or considerable wear on the stage.
►
Avoid motion in open-loop operation.
►
If motion is necessary in open-loop operation: Stop the positioner in time. For this
purpose, use the
#24 , STP or HLT command, or set the control value to zero with the SMO
command.
►
Do not choose parameter settings that would deactivate limit switch evaluation by the
electronics.
► Check the function of the limit switches at about 10 % to 20 % of the maximum velocity.
►
In the event of a malfunction of the limit switches, stop the motion immediately.
NOTICE
Selection of an incorrect positioner type!
Selection of an incorrect positioner type in the PC software can cause damage to the
positioner.
►
Make sure that the positioner type selected in the PC software matches the positioner
connected.
NOTICE
Oscillation!
Unsuitable settings of the notch filter and the E-871.1A1N's servo control parameters can
cause the positioner to oscillate. Oscillation can damage the positioner and/or the load fixed
to it.
►
Secure the positioner and all loads adequately.
►
If the stage is oscillating (unusual operating noise), switch off servo mode or the
E-871.1A1N immediately.
► Switch servo mode back on only after you have changed the E-871.1A1N's notch filter
settings and servo control parameters; see "
Adjusting the Notch Filter (p. 62) " and
" Optimizing the Servo Control Parameters (p. 67) ".
►
If a very high load causes oscillation during the reference move, follow the instructions
on the reference move under
"Troubleshooting" (p. 214) .
Starting motion with PIMikroMove
1. When the
Stage Type Configuration
dialog has opened: Click the
Yes, configure for ...
button to load the matching parameter set from a positioner database into the
E-871.1A1N.
