6.3 Examples of I/O Signal ConnectionsNote: 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 inputsignals 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 SignalsSignal Name Pin No. Function ReferenceALM+ 31 Servo alarm: Turns OFF when an error is detected. 8.11.1ALM- 32CommonSpeedPositionReserved/TGON+/TGON-/S-RDY+/S-RDY-PAO/PAOPBO/PBOPCO/PCOPSO/PSOALO1ALO2ALO32728293033 (1)34353619204849373839 (1)Detection during servomotor rotation: Detects when the servomotor is rotatingat a speed higher than the motor speed setting. Detection speed can be set by usingthe parameters.Servo ready: ON if there is no servo alarm when the control/main circuit powersupply is turned ON.Phase-A signalPhase-B signalPhase-C signalPhase-S signalConverted two-phase pulse (phases A and B) encoder outputsignal and zero-point pulse (phase C) signal: RS-422 or theequivalent(Proper line receiver is SN75175 manufactured by TexasInstruments or the equivalent corresponding to MC3486.)With an absolute encoder: Outputs serial data correspondingto 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 maximumFG Shell Connected to frame ground if the shield wire of the I/O signal cable is connectedto the connector shell.25 Speed coincidence (output in Speed Control Mode): Detects whether the motor26 speed is within the setting range and if it matches the reference speed value./V-CMP+/V-CMP-/COIN+/COIN-2526/CLT −/VLT/BK/WARN/NEAR− 1617232450Positioning completed (output in Position Control Mode): Turns ON when thenumber of positional error pulses reaches the value set. The setting is the number ofpositional error pulses set in reference units (input pulse units defined by the electronicgear).Reserved terminalsThe functions allocated to /TGON, /S-RDY, and /V-CMP (/COIN) can be changed byusing the parameters. /CLT, /VLT, /BK, /WARN, and /NEAR signals can also bechanged.Terminals not usedDo not connect relays to these terminals.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 theparameters. /CLT, /VLT, /BK, /WARN, and /NEAR signals can also be changed.
