6.
Divide the voltage/current corresponding to maximum velocities by
the full range of the clamp open valve(s) input level to determine the
percent signal outputs for maximum. Enter these values into FOC48,
SOC48, TOC48, and OSC48.

Test Your Clamp Open Velocity Valve(s) for Linearity
1.
Select velocity vs. position control for the entire Clamp Open
operation by resetting (= 0) the following four bits:
OPC03-B00 (Pro-Set 600 address B37:608)
OPC03-B02 (Pro-Set 600 address B37:610)
OPC03-B04 (Pro-Set 600 address B37:612)
OPC03-B06 (Pro-Set 600 address B37:614)
2.
Select setpoints for Clamp Open that are typical of the velocities you
would run during normal machine operation. Enter these setpoints
into OPC09, OPC12, OPC15, and OPC36 (Pro-Set 600 addresses
N43:545, N43:548, N43:551, and N43:572).
3.
Download changes to the QDC module (refer to chapter 4 for detailed
instructions).
4.
Jog your clamp to the full close position (mold halves mated).
5.
Enable First Clamp Open (DYC02-B10, Pro-Set 600 address
B35/410). The clamp should move from its start position through the
First Clamp Open Profile, and then execute Open Slow. If no motion
is observed, check the following:
- Verify that none of your clamp or ejector overtravel alarms are set.
The QDC module inhibits clamp open if SYS07-B00 through
SYS07-B05 are set
- Verify that no programming error codes exist in SYS61 and
SYS62
6.
Upon completion of Clamp Open, observe the velocity reported back
for 1st clamp open segment 2 (OPS12, Pro-Set 600 address
N43:720). This velocity should be relatively close to the setpoint you
entered in OPC12 (Pro-Set 600 address N43:548). If the observed
velocity is not within 25% of the setpoint:
- Verify you chose the correct values from your flow rate curves
supplied by your flow valve manufacturer
- Verify your calculations
