Potentiometer nr. Function Start position
RP1 offset feedback minimal = completely turned
to the right
RP2 gain feedback maximal = completely turned
to the left
RP4 gain braking on Y-brake minimal = completely turned
to the left
RP5 slip factor minimal = completely turned
to the left
RP6 gain differential minimal = completely turned
to the left
C The potentiometers RP3, RP7, RP8, RP9 and RP10 are factory set to optimal values.
Adjustment procedure part support
C Go to the diagnostic mode
C Select DM01 module that controls the part support.
C Move cursor to the speed output parameter ‘output0' with cursor key.
C Select 0 (= 0%).
C Start the machine and the hydraulic pump of the part support construction.
C Follow the next adjustment procedures:
** Adjustment of the feedback offset (see O1 in the blockdiagram of principle PID-
controller)
C Turn RP1 until the part support is in the horizontal position.
In case the part support can not be adjusted in an optimal way turn potentiometer RP6 a
couple of turns to the right.
** Adjustment of the feedback gain (see A1 in the blockdiagram of principle PID-
controller)
C Select 50% of ‘output0'. This corresponds with the value 127.
C Turn potentiometer RP2 until the part support brackets are exactly halfway the maximum
required angle.
** Adjustment of the differential gain (see A3 in the blockdiagram of principle PID-
controller)
C Leave the diagnostic program.
C Program the part support machine parameters before continuing this procedure. See
section 9.3.
C Select the manual mode.
C Program the manual mode parameters and program the pressing speed not too high, e.g. 2
mm/s.
C Make some pressing movements and turn potentiometer RP6 during the pressing phase
so, that the part support is not oscillating and following the pressing movement fluently.
** Adjustment of the slipfactor (differentiating gain D in the blockdiagram of principle PID-
controller)
