How do I apply a filter to motor speed readings over MEMOBUS/Modbus communications?

You can apply a filter to motor speed readings by setting parameter H5-18 [Motor Speed Filter over Comms], which sets the filter time constant in milliseconds (range: 0 to 100 ms, default: 0 ms). This filter applies to MEMOBUS/Modbus registers 003EH, 003FH, 0044H, 00ACH, and 00ADH, which correspond to output frequency and motor speed (U1-05) values. (Page 10)
