By setting this parameter, the direction of the input pulse can be reversed. At this time the actual
output speed direction of the servo drive is opposite to the direction indicated by the pulse input
form in P0.23.
Setting value Pulse input
[0] Pulse input direction does not change
1 Pulse input direction is opposite to the original input direction

Concept of the electronic gears: for any pulse input, the number and frequency of the pulse
actually received by the drive can be changed by multiplying a certain coefficient and this
coefficient is electronic gear ratio. It can be indicated in two parts: numerator and denominator:
Electronic gear ratio = g1/ g2;
Of which
g1: The numerator of the electronic gear ratio;
g2: The denominator of the electronic gear ratio;
