6.3.5 I/O Signal (CN1) Names and Functions
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.

Servo alarm: Turns OFF when an error is detected.
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.
Servo ready: ON if there is no servo alarm when the control/main circuit power
supply is turned ON.
Phase-A signal
Converted two-phase pulse (phases A and B) encoder output
signal and zero-point pulse (phase C) signal: RS-422 or the
Phase-B signal equivalent
(Proper line receiver is SN75175 manufactured by Texas
Instruments or the equivalent corresponding to MC3486.)
Phase-C signal
With an absolute encoder: Outputs serial data corresponding
Phase-S signal
to the number of revolutions (RS-422 or the equivalent)
Alarm code output: Outputs 3-bit alarm codes.
Open-collector: 30 V and 20 mA 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 positional error pulses reaches the value set. The setting is the number of
positional error pulses set in reference units (input pulse units defined by the elec-
tronic gear).
Reserved terminals
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.
Terminals not used
Do not connect relays to these terminals.
