PPR/CPR X1 X2 X4 to degrees.

Inputs

Encoder and count

Encoder lines per revolution.

X1 counts lines, X2 doubles, X4 quadruples.

Counted pulses from the decoder.

Verify

Check before relying.

Counts mean nothing without PPR.

  • Nameplate PPR matches the setting
  • X1/X2/X4 matches the decoder
  • Index pulse seen once per rev
This calculator is a first-pass screening tool. Verify nameplate data, wiring, module configuration, and calibrator readings before acting.
