This document describes best practices for using Red Lion counters.
Red Lion Counters
- NPN inputs are recommended for Red Lion counters.
- PNP inputs may also be used, but require a jumper or switch change in most cases.
- Scale factors greater than 1 cause rounding errors.
- The closer the scale factor is to 1 (but not over), the better the accuracy.
- The more pulses per unit, the better the precision.
- For each desired digit after the decimal places, you need 10 pulses. I.E. for 2 digits after the D.P, you want 100 pulses, 3 digits - 1000 pulses.
- When the scale factor is not 1, the least significant digit may be off by 1.
- Each count mode has a different maximum input frequency, refer to the Maximum Signal Frequencies chart in the counter's manual.
- Use quadrature signals for bidirectional counting.
- If you have a quadrature encoder, and the counter supports it, it should be used as long as the input frequency will not be exceeded.
