Puller - Encoder Input

Puller Encoder Input is used to scale the encoder input of the lower belt for a

Follower application. Two presets are used. In the example, the amount of counts

per motor revolution are used. The scaling shown in this example matches a simi-

lar style of puller. The motors on the pullers have 2,048 pulses per motor revolu-

tion on both A and B channels. The system uses quadrature x 4 meaning that all

four phase changes are counted for a total of 8,192 counts per motor revolution.

To change the amount of Puller Encoder Input revolutions:

1 Press the Puller section’s Encoder Input Revolutions window. A numeric

pop-up keyboard appears.

2 Key in the new revolution amount. This is the number of revolutions the

puller shaft will rotate.

3 Then press “Enter”. The pop-up keyboard is removed.

NOTE: Refer to your specific style of puller encoder to properly scale the amount of counts per

motor revolutions.
