Note: 1. Pin numbers in parentheses () indicate signal grounds.
2. The functions allocated to /S-ON, /P-CON. P-OT, N-OT, /ALM-RST, /P-CL, and /N-CL input
signals can be changed by using the parameters. Refer to
7.3.2 Input Circuit Signal Allocation
.
3. The voltage input range for speed and torque references is a maximum of
±
12 V.
(2) Output Signals
Note: 1. Pin numbers in parentheses () indicate signal grounds.
2. The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed by using the
parameters. /CLT, /VLT, /BK, /WARN, and /NEAR signals can also be changed. Refer to

Positioning completed (output in Position Control Mode): Turns ON when the
number of positional error pulses reaches the value set. The setting is the num-
ber of positional error pulses set in reference units (input pulse units defined by
the electronic gear).
