Encoder Frequency to RPM

Hz to RPM at effective CPR.

Inputs

Signal and encoder

Pulse frequency from the counter.

Nameplate pulses per revolution.

Decoder multiplier: 1, 2, or 4.

Limits and mechanics

Maximum input frequency of the high-speed counter.

Set for linear speed; 0 skips line-speed outputs.

Check before relying.

Frequency divided by PPR.

  • Counter gate time suits the speed
  • X4 multiplies effective PPR
  • Counter limit above max frequency
This calculator is a first-pass screening tool. Verify nameplate data, wiring, module configuration, and calibrator readings before acting.
