Chap. 5 FUNCTION CODES
Pulse train sign/Pulse train input
Forward rotation pulse/Reverse rotation pulse
A and B phases with 90 degree phase difference
Pulse count factor 1 (d62), Pulse count factor 2 (d63)
For the pulse train input, function codes d62 (Command (Pulse rate input), (Pulse count factor 1)) and d63 (Command
(Pulse rate input), (Pulse count factor 2)) define the relationship between the input pulse rate and the frequency
command (reference).

Relationship between the Pulse Train Input Rate and Frequency Command (Reference)
As shown in the figure above, enter the pulse train input rate into function code d62 (Command (Pulse rate input),
(Pulse count factor 1)), and enter the frequency reference defined by d62 into d63 (Command (Pulse rate input), (Pulse
count factor 2)). The relationship between the pulse train input rate (kp/s) inputted to the PIN terminal and the
frequency reference f* (Hz) (or speed command) is given by the expression below.

In the case of A and B phases with 90 degree phase difference, note that the pulse
train rate is not the one 4-multiplied.
