Function
Servo alarm: Turns OFF when an error is detected.
Detection during servo motor rotation: detects when the servo motor 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 equivalent
(proper line receiver is SN75175 manufactured by Texas Instruments or the equivalent
Phase-B signal
corresponding to MC3486.)
Phase-C signal
Phase-S signal With an absolute encoder: Outputs serial data corresponding 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
Analog monitor signal
Analog monitor signal
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 electronic 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.
