4 Inputs and Outputs4.4.1 Using a Rotary Servo Motor184.4 I/O Signal Wiring Examples4.4.1 Using a Rotary Servo Motor* 1. represents twisted-pair wires.* 2. Connect these when using an absolute encoder. If the Encoder Cable with a Battery Caseis connected, do not connect a backup battery.* 3. The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply withdouble insulation or reinforced insulation.* 4. Always use line receivers to receive the output signals.Note: 1. You can use parameters to change the functions allocated to the /SI0, /SI3,P-OT, N-OT, /EXT1, /EXT2, and /EXT3 input signals and the /SO1, /SO2,and /SO3 output signals.2. If you use a 24-V brake, install a separate power supply for the 24-VDCpower supply from other power supplies, such as the one for the I/O signalsof the CN1 connector.If the power supply is shared, the I/O signals may malfunction./BK+/BK-/SO2+/SO2-/SO3+ALM+ALM-12232434+24VIN+24 V *3 4.7 kΩ681091112/SI0P-OTN-OTGeneral-purposesequence input 0BAT+BAT-1314157/SO3-Forward Drive Prohibit input(prohibited when OFF)Sequence input signalpower supply inputBattery forabsolute encoderBackup battery*22.8 V to 4.5 VReverse Drive Prohibit input(prohibited when OFF)Brake output(released when ON)Servo Alarm Output(OFF for alarm)252616 SG*1PBOPCO/PBOPAO/PAO/PCO211718192022FGCN1*4*4*4Photocoupler outputsMax. allowable voltage: 30 VDCMax. allowable current: 50 mA DCEncoder DividedPulse Output,Phase AEncoder DividedPulse Output,Phase BEncoder DividedPulse Output,Phase CApplicable LineReceiver:SN75ALS175 orMC3486manufacturedby TexasInstruments orthe equivalentConnect shield to connector shell.ConnectorshellSERVOPACKFrame groundSignal ground/SI3/EXT1/EXT2/EXT3External latch signal 1 input(General purpose input 4)General-purposesequence input 3External latch signal 2 input(General purpose input 5)External latch signal 3 input(General purpose input 6)+-
