Output A
Pulse + / Pulse / Pulse Phase A: + direction dive pulse outputting
It is Low level at reset, and when driving is started, DUTY 50% (at
constant speed) of the plus drive pulses is output.
When the 1-pulse 1-direction mode is selected, this terminal is for drive
output.
When the quadrature pulse mode is selected, this terminal is for A-phase
signal output.

Output A
Pulse - / Direction / Pulse Phase B:
− direction dive pulse outputting
It is Low level at reset, and when driving is started, DUTY 50% (at
constant speed) of the plus drive pulses is output.
When the 1-pulse 1-direction mode is selected, this terminal is the
direction signal.
When the quadrature pulse mode is selected, this terminal is for B-phase
signal output.

Encoder-A / Pulse+in: signal for encoder phase-A input
This input signal, together with phase-B signal, will make the Up / Down
pulse transformation to be the input count of real position counter.
When the Up / Down pulse input mode is selected, this terminal is for UP
pulses input. When
the input pulse is up (↑), the real position counter is
counted up.

Encoder-B / Pulse-in: signal for encoder phase-B input
This input signal, together with phase-A signal, will make the Up / Down
pulse transformation to be the input count of real position counter.
When the Up / Down pulse input mode is selected, this terminal is for
DOWN pulses input. When
the input pulse is up (↑), the real position
counter is counted down.

0: input signal to perform decelerating / instant stop
These signals can be used for HOME searching. When the filter function is
disabled, the active pulse width must be 2CLK or more. Enable / disable
and logical levels can be set for STOP2
～
STOP0.
In automatic home search, STOP0 can be assigned to a near home
search signal, STOP1 to a home signal and STOP2 to an encoder
Z-phase signal.
The signal status can be read from
RR3 register Page0.

Input B
－Ｆ－
Over Run Limit +: signal of + direction over limit
During the + direction drive pulse outputting, decelerating stop or instant
stop will be performed once this signal is active. When the filter function is
disabled, the active pulse width must be 2CLK or more. Enable / disable,
decelerating stop / instant stop and logical levels can be set as
commands. When the limit signal is enabled and this signal is in its active
level direction driving, HLMT+ bit of RR2 register becomes 1. The
signal status can be read from RR3 register Page0, and this signal can be
used to search a home position.

Over Run Limit -:
signal of − direction over limit
During the − direction drive pulse outputting, decelerating stop or instant
stop will be performed once this signal is active. When the filter function is
disabled, the active pulse width must be 2CLK or more. Enable / disable,
decelerating stop/instant stop and logical levels can be set as commands.
When the limit signal is enabled and this signal is in its active level during
− direction driving, HLMT− bit of RR2 register becomes 1. The signal
status can be read from RR3 register Page0, and this signal can be used
to search the home position.

Inposition: input signal for servo driver in-position
Enable/disable and logical level can be set as commands. When enabled
and after driving is finished, DRIVE bit of main status register returns to 0
after this signal becomes active.
The signal status can be read from RR3 register Page0.
