• Input terminal for position command pulse. You can select by setting up
Pr40 (Selection of command pulse input) to 1.
• This input becomes invalid at such control mode as velocity control or
torque control, where no position command is required.
• Permissible max. input frequency is 2Mpps.
• You can select up to 6 command pulse input formats with Pr41 (Setup of
command pulse rotational direction) and Pr42 (Setup of command pulse
input mode).
For details, refer to the table below, "Command pulse input format".

• Input terminal for the position command. You can select by setting up Pr40
(Selection of command pulse input) to 0.
• This input becomes invalid at such control mode as the velocity control or
torque control, where no position command is required.
• Permissible max. input frequency is 500kpps at line driver input and
200kpps at open collector input.
• You can select up to 6 command pulse input formats with Pr41 (Setup of
command pulse rotational direction) and Pr42 (Setup of command pulse
input mode).
For details, refer to the table below, "Command pulse input format".
• Pulse train interface
Input Signals (Pulse Train) and Their Functions
You can select appropriate interface out of two kinds, depending on the command pulse specifications.
• Pulse train interface exclusive for line driver

• Permissible max. input frequency of command pulse input signal and min. necessary time width
Set up the rising/falling time of command pulse input signal to 0.1 µ s or shorter.
• PULS and SIGN repre-
sents the outputs of pulse
train in put circuit. Refer
to the fig. of P.84, "Input
Circuit".
• In case of CW pulse train
+ CCW pulse train and
pulse train + sign, pulse
train will be cap tured at
the rising edge.
• In case of 2-phase pulse,
pulse train will be cap-
tured at each edge.
