(2) Pulse train form selection (PP, NP signal) [Pr. 428]
Command pulse can be changed according to the
positioning unit as in the table below.
Command Pulse Train Form
Forward rotation pulse train
Reverse rotation pulse train
Pulse train + rotation direction sign
A phase pulse train
B phase pulse train
Forward rotation pulse train
Reverse rotation pulse train
Pulse train + rotation direction sign
A phase pulse train
B phase pulse train
(3) Interface of the positioning unit and inverter
When running the inverter by each positioning unit,
interface of the positioning command pulse train
need to be matched.

Remarks
QD75D(CW/CWW mode)
(Note) If (CW/CWW mode) and (PLS/
SIGN mode) are mistaken, the motor
runs only in one direction.
QD75D (PLS/SIGN mode)
Counted after multiplying by four.
Set the pulse train frequency multiplied
by four to 500kpps or less with the
differential driver type and to 200kpps or
less with the open collector type.
Counted after being multiplied by four.
Set the pulse train frequency multiplied
by four to 500kpps or less with the
differential driver type and to 200kpps or
less with the open collector type.
