NOTE
If precise measurements are necessary, it is recommendable to
adjust the output voltage once (this will not prevent a position
output drift).
Procedure
Ø Reference gripper "internally" or "externally".
Ø Insert gauge blocks with regard to the gripping positions
approached later.
Ø Open or close gripper.
Ø Measure the output voltage for each gauge block and use it as
the reference voltage for the respective position.
During operation of the gripper in the automated system, these
reference voltages can then be compared with the analog output
signal "Position output" (terminal 15) (e.g. in order to start further
actions). Depending on the required precision and due to the
position output drift, all x-cycles must be re-referenced (High
signal on "Reference run [terminal 19] + High edge on "Gripper
open" (terminal 21) or "Gripper closed" (terminal 20). In the case
of high demands on the precision of the output "Analog position
output", we recommend performing a reference run before each
gripping cycle.
(x must be determined experimentally in the application)
