Note: 1. When
P.550 =57
and the toggle switch SW11 is switched to HDI, the HDI input function is valid.
2. The frequency computing method of HDI input signal is similar to 2-5 analog input, the formula is
P.1 * ((P.525-P.524)*(P.523-P.522)/(the input frequency– P.524) + P.522).

•
P.532 is “PTC filter coefficient”, and it is used to filter out the operation frequency jitter
generated by component accuracy, noise or other factors. The larger the set value of
P.532 is, the better the filter ability is, and the slow response will be caused.
