Orient Complete
Closed: The machine is within the orient position window established by P1-05 and the P1-07 ORT Set Time has expired. Once this condition is
met, the output remains closed as long as the machine is within the P1-06 window.

Error
CDEV
Marker Det Error
<3Ch>
The drive monitors the number of A and B channel
encoder pulses between each marker pulse
(Z or C channel). There should be F1-01
(Encoder PPR) A and B channel pulses between
each marker pulse. If the pulse count exceeds F1-01
x 8, the drive displays a CDEV fault and coasts to a
stop.
Note: If Orientation encoder parameter P1-10 = 1,
parameter F1-31 sets Encoder PPR. If an Indirect
Drive configuration is used, Orientation encoder
PPR is multiplied by the active gear ratio.
This fault is displayed when the motor has gone two
rotations without receiving a marker pulse from the
motor encoder (Z or C channel).
This could be caused by disconnected or
malfunctioning hardware, or inappropriate
parameter settings.
This fault is only triggered while an orient digital
input is activated and the frequency reference is less
than the P1-01 Orient Speed.
- Remove all run commands from the drive. Check
the wiring of the encoder, especially the Z pulse.
- Check for noise on the encoder feedback signals.
- Check the F1-01/F1-31 parameter setting matches
the encoder being used.
