3. Record this position value (normally 0000) on line 1 for MCC09 on
Worksheet 3-E.
4. With your programming terminal, read the signal level returned in
SYS33 (N40:185) from your position sensor. You may wish to zero
your position sensor at this time.
5. Record this value on line 3 for MCC11 (should be at minimum signal
if you zeroed your position sensor in step 4).
6. Move the ram (screw) backward to the backpoint mechanical stop.
7. Remove ram (screw) pressure and/or flow to stop movement.
8. Measure the distance travelled.
9. Record this distance on line 2 for MCC10.
10. With your programming terminal, read the signal level returned in
SYS33 (N40:185) from your positioning sensor. You may wish to
span your position sensor at this time.
11. Record this value on line 4 for MCC12.
You may now download your adjusted values to the QDC module using
the MCC download procedure presented earlier in this chapter.
Determine Values for the Clamp Position Sensor
Important: Use the following procedure and subsequent set-up
information for each different mold used on a hydraulic machine. On a
toggle clamp (with die height adjust), complete it only once.
ATTENTION: Incorrect values entered in DYC09-12 may
result in rapid clamp motion and potential damage to your mold
or cylinder seals. We strongly recommend using a “dummy”
mold on hydraulic machines and no mold on toggle machines.
Important: If your position sensor has zero and span potentiometers to set
the zero reference and linear resolution, do so during this procedure.
1. Move the clamp forward until it reaches its mechanical close stop.
This is the zero position.
2. Remove clamp pressure and/or flow to stop clamp movement.
