4.5 Connecting I/O Signals4.5.3 I/O Signal Wiring Examples4-314 Wiring and Connecting SERVOPACKs4.5.3 I/O Signal Wiring ExamplesUsing a Rotary Servomotor*1. represents twisted-pair wires.*2. Connect these when using an absolute encoder. If the Encoder Cable with a Battery Case is connected, do notconnect a backup battery.*3. The 24-VDC power supply is not provided by Yaskawa. Use a 24-VDC power supply with double insulation orreinforced 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, /Probe1, /Probe2,and /Home input signals and the /SO1, /SO2, /SO3, /SO4, and /SO5 output signals.7.1 I/O Signal Allocations on page 7-42. If you use a 24-V brake, install a separate power supply for the 24-VDC power supply from other powersupplies, such as the one for the I/O signals of the CN1 connector.If the power supply is shared, the I/O signals may malfunction.4.7 kΩGeneral-purposesequence input 0Forward 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)*1*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 line receiver:SN75ALS175 or MC3486manufactured by TexasInstruments or the equivalentSERVOPACKSignal groundProbe 1 Latch Input(latch when ON)General-purposesequence input 3Probe 2 Latch Input(latch when ON)Home Switch Input(homing when ON)/BK+/BK-ALM+ALM-1234+24VIN+24 V *3 681091112/SI0P-OTN-OT/SI3/Probe1/Probe2/HomeBAT+BAT-1314157/SO2+/SO2-/SO3+2324/SO3-2526/SO4+/SO4-/SO5+2728/SO5-2930CN116 SGPBOPCO/PBOPAO/PAO/PCO211718192022+-
