Modify this parameter if the encoder is attached to a gear box rather than connected directly to the rotor.  In most applications this is set to 1.

Signal Order

A leads B

Select one of the following options:

  • A leads B - A is the first output pulse as the machine begins to rotate
  • B leads A - B is the first output pulse as the machine begins to rotate

If the machine appears to be turning backwards, consider switching this setting.

Angle OffsetθOffsetDegrees0°Angle offset applied to the machine angle, θmach
Polarity

Active Low

Select one of the following options:

  • Active High - Output signals are pulled High to signify an encoder pulse
  • Active Low - Output signas are pulled Low to signify an encoder pulse
Pulses Per Revolutionppr
