Pickmaster 3 - PPACAL Problem

dhyan

Dear All

We got a problem with doing first step on Pickmaster 3 setting (calculate Count per Meter), because we failed to do PPACAL.
After we do PPACAL, On jogging menu : CNV1 is activated and distance show 0.0 mm.
When I run conveyor, diplay show a positif value (higher than 0.0 ) .
But when I stop conveyor, the value go back to 0.0.
the value should be hold on the current value, if we can do PPACAL successfully.

Here our Strobe Wiring Diagram (attachment file):
The doManSync1 (connector: X2.1, unit mapping: 8) is connected to Start Signal (pin-9) on Encoder Unit.
The Strobe of camera (Black wire) is connected to Start Signal (pin-9) on Encoder Unit too.

Last time we got the same problem (few years ago):
When we disconnected the strobe of camera from pin-9 Encoder board (now only doManSync1 is connected to pin-9), the problem was gone.
We can do PPACAL (The doManSync1 LED on I/O board is flash once) and the position value is hold on the current value.

But today, we got another problem:
When we disconnect the strobe of camera to pin-9 Encoder board (now only doManSync1 is connected to pin-9), the problem is still happened.
We failed to do PPACAL (The doManSync1 LED on I/O board is not flash at all) and the position value will go back to 0.0 everytime we stop conveyor.

Is there someone who has an idea about this problem?

Thanks and regards
