Setting up a Pre-Condition for complex capture

Setting the Precondition Edge: (Terminal Command: CAP0.PREEDGE)
The pre-edge determines what input state change triggers the precondition. This feature operates the
same as the capture edge described above.
Setting the Pre-Condition Select: (Terminal Command: CAP0.PRESELECT)
The preselect chooses what input source will trigger the precondition (based on the preedge setting, and
the prefilter setting). This feature operates the same as the capture source described above.

7.6.3 Kollmorgen Test Reports

Position Capture test report based on performance testing by Kollmorgen:
Capture Accuracy with External Sensor
Drive: AKD-T00306-NBAN-000
Motor: AKM-21C
Feedback Type: Incremental type 2048 line encoder
Digital Input used: DIN1
DIN1.FILTER = 0
does not delay the system response)
Sensor Used : IDC RP1 type mounted directly to the shaft. Common
industrial limit switch.
MOVE.RUNSPEED = 1000 RPM
With the motor running at above speed and the capture mechanism
armed, the drive was able to capture the position within 30-70
counts (.17 - .40 degree) of accuracy or 27.5 – 64.0 micro sec.
Capture Accuracy with Internal Index from encoder
Drive - AKD-T00606-NBAN-000
Motor-AKM22G
Feedback Type – Incremental Encoder 2048 lines
MOVE.RUNSPEED = 1000 RPM
With the motor running at above speed and the capture mechanism
armed, the drive was able to capture the position within 10-20
counts (.05 - .11 degree) of accuracy or 9.5 – 18.0 micro sec.
