*1 The electric maximum response frequency is specified by resolution (pulse number) and the maximum number of revolutions.
Electrical maximum number of revolutions = {(Maximum response frequency/Resolution) x 60}
Therefore, if the encoder rotates at a speed greater than the electrical maximum number of revolutions, the signals do not electrically follow.
*2 The totem-pole output is 100 kHz and the line driver output is 200 kHz.
