The information I know is written in the NAV description (see attachment, special the red text): For each incremental interface there are twocounters on the board (in one chip). One counts the pulses the other one the "time",a 16 MHz signal( if the task time is below 20ms). Thevalues are read out and the speed is calculated every task time (TA). The task time can be defined between 100µs an some seconds (typically it's 1 ms) I would be much easyer to answer you,if you define "slow speed" and tell us the data of the encoder you want to use. Or, if you want to meter a frequency, the range area it is in. AttachmentNAV.pdf (458 Downloads) |
