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 7.3.3

35 Servo alarm: Turns OFF when an error is detected. 8.11.1
/TGON 9 (10) 9 (10) Detection during servomotor rotation: Detects when the servomotor is rotating
at a speed higher than the motor speed setting. Detection speed can be set by
using the parameters. 8.11.3
/S-RDY 7 (10) 7 (10) Servo ready: ON if there is no servo alarm when the control/main circuit power
supply is turned ON. 8.11.4

FG Shell Connected to frame ground if the shield wire of the I/O signal cable is connected
to the connector shell. −
Speed /V-CMP 8 (10) − 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. 8.5.8
Position /COIN − 8 (10) 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). 8.6.5
