Note 1. The functions allocated to /S–ON, /P–CON. P–OT, N–OT, /ALM–RST, /P–CL, and /N–CL input
signals can be changed with parameters. (See 5.3.3 Input Circuit Signal Allocation.)
2. Pin numbers in parenthesis ( ) indicate signal grounds.
3. The voltage input range for speed and torque references is a maximum of ±12V.

The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed via parame-
ters. Functions /CLT, /VCT, /BK, /WARN, and /NEAR signals can also be changed. (See 5.3.4 Out-
put Circuit Signal Allocation).
Input mode
Corresponds to refer-
ence pulse input
• Code + pulse string
Line–driver
• CCW/CW pulse
Open–collector
• Two–phase pulse (90° phase differential)
+12V pull–up power supply when PULS, SIGN and CLR reference signals
are open–collector outputs (+12V power supply is built into the servo ampli-
fier).
Servo alarm: Turns OFF when an error is detected.
Detection during servomotor rotation: Detects whether the servomotor is rotating at a
speed higher than the motor speed setting. Motor speed detection can be set via parame-
ter.
Servo ready: ON if there is no servo alarm when the control/main circuit power supply is
turned ON.
A phase signal
Converted two-phase pulse (A and B phase) encoder output signal and
B phase signal
origin pulse (C phase) signal: RS-422 or the equivalent.
C phase signal
With an absolute encoder: Outputs serial data corresponding to the
S phase signal
number of revolutions (RS-422 or equivalent).
Alarm code output: Outputs 3-bit alarm codes.
Open–collector: 30V and 20mA rating maximum.
Connected to frame ground if the shield wire of the I/O signal cable is connected to the
connector shell.
Speed coincidence (output in Speed Control Mode): Detects whether the motor speed is
within the setting range and if it matches the reference speed value.
Positioning completed (output in Position Control Mode): Turns ON when the number of
error pulses reaches the value set. The setting is the number of error pulses set in refer-
ence units (input pulse units defined by the electronic gear).
These terminals are not used.
Do not connect relays to these terminals.
