Encoder Scaling
This menu is used to display the encoder type and configure the encoder
scaling. The pattern controller automatically detects the type of encoder
installed. If no encoder is detected the pattern controller is set to timer
mode. The encoder scaling ratio is determined by entering the number of
pulses per millimeter that the encoder outputs when installed. If a
quadrature encoder is used, the direction of rotation travel maybe reversed.

or
&
button for the cursor to appear beside Custom.
b. Press the
"
or
#
button to set the encoder gearing ratio from
0.001 – 20.000 ppmm (pulses per millimeter).
2. To set the encoder direction:
Press the
"
or
#
button to set the direction to Forward or Backward.
NOTE:
The direction parameter is used only if a quadrature encoder is
detected.
