Output Signals
Note 1. Pin numbers in parenthesis () indicate signal grounds.
2. The functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed via
parameters. Functions /CLT, /VCT, /BK, /WARN, and /NEAR signals can also be changed. (See
5.3.4 Output Circuit Signal Allocation )

Servo alarm: Turns OFF when an error is detected. 5.5.1
/TGON+
/TGON-

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 parameter.

A phase signal
B phase signal
C phase signal
Converted two-phase pulse (A and B phase) encoder
output signal and origin pulse (C phase) signal: RS-422
or the equivalent.

S phase signal
With an absolute encoder: outputs serial data
corresponding to the number of revolutions (RS-422 or
equivalent).

Alarm code output: Outputs 3-bit alarm codes.
Open-collector: 30V and 20mA rating maximum.
5.5.1
FG Shell
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.
5.5.4
Position /COIN+
/COIN-
25
26
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 reference units (input pulse units defined by
the electronic gear).
