3 Wiring and Connection3.3.5 Example of I/O Signal Connections in Torque Control3-283.3.5 Example of I/O Signal Connections in Torque ControlConnection example in torque control is as shown below.∗1. represents twisted-pair wires.∗2. Connect when using an absolute encoder. When the encoder cable with the battery case is connected, do not connecta backup battery.∗3. Enabled by the parameter setting.∗4. The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-tion.∗5. When using the safety function, a safety function device must be connected and the wiring that is necessary to acti-vate the safety function must be done to turn ON the servomotor power. When not using the safety function, use theSERVOPACK with the Plug (provided as an accessory) inserted into the CN8.∗6. Always use line receivers to receive the output signals.BAT(+)BAT(-)PBOPCO/PBOPAO/PAO/PCO/VLT+/VLT-/TGON +/TGON -/S-RDY+ALM+ALM-2221102728293031322526193334353620+24 V +24VIN 3.3 kΩ/S-ON/P-CONP-OTN-OT/ALM-RST/N-CL474143424445/P-CL4640/S-RDY-V-REFSG A / D56T-REFSG92+5 V0 VSENSG4ALO1ALO2ALO33738391 SGFG/HWBB1+/HWBB1-/HWBB2+/HWBB2-6345CN8CN1D/AD/AEDM1+EDM1-87*2SERVOPACK*1*4*2*3Backup battery2.8 to 4.5 VServo ON(Servo ON when ON)Reverse run prohibited(Prohibited when OFF)Forward run prohibited(Prohibited when OFF)Alarm reset(Reset when ON)Reverse external torque limit(Limit when ON)Forward external torque limit(Limit when ON)P control(P control when ON)Rotation Detection output(ON when the motor speedexceeds the settings.)Servo alarm output(OFF for an alarm)Photocoupler outputMax. operating voltage:30 VDCMax. output current:50 mA DCSpeed limit output *3(ON when the motor'srunning speed is limited.)Torque reference(Max. inputvoltage range:± 12 V)SEN signal inputMax. operating voltage: 30 VDCMax. output current: 20 mA DCExternal speed limit(Max. inputvoltage range:± 12 V)Servo ready output(ON when ready)Connect shield toconnector shell.ConnectorshellSERVOPACKSwitchFuse24 V0 VSafety function device *5Alarm code output (OFF for alarm)Encoder outputpulse phase AEncoder outputpulse phase BEncoder outputpulse phase CApplicable line receiver:SN75ALS175 orMC3486 manufacturedby Texas Instruments orthe equivalent*6*6*6Analog
