2.1.3.1 Pulse Input (PPI, CA, *CA, CB, *CA)
Pulse input terminal

Format: Command pulse/direction, forward/reverse pulse, A/B phase pulse (parameter switch)

Max. input frequency: 4[MHz] (differential input), 200[kHz] (open collector input)
The 90° phase difference 2 signal is the frequency after multiplying by four. It is normally a multiple
of four.
(1) Differential input
Do not use the PPI terminal.
(2) Open collector (24 [V] DC)
Use the PPI terminal.
* The wiring with the host should be 3 m or less.
(3) Open collector output (12 [V] DC)
Use a resistor (470 Ω, 1W), without a PPI terminal, and wire as follows.
* The wiring with the host should be 3 m or less.
Resistors (470Ω) may generate heat.
