3.3 I/O Signal Connections3-193 Wiring and Connection3.3.3 Example of I/O Signal ConnectionsThe following diagram shows a typical connection example.∗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. The 24-VDC power supply is not included. Use a 24-VDC power supply with double insulation or reinforced insula-tion.∗4. Always use line receivers to receive the output signals.Note: The functions allocated to the input signals /DEC, P-OT, N-OT, /SI0, and /SI4 to /SI6 and the output signals /SO1,/SO2, and /SO3 can be changed by using the parameters.Refer to 3.4.1 Input Signal Allocations and 3.4.2 Output Signal Allocations.Homing deceleration switch(Decelerated when ON)Control power forsequence signalsExternal latch signal 1(Latched when ON)Reverse run prohibited(Prohibited when OFF)External latch signal 2(Latched when ON)External latch signal 3(Latched when ON)Backup battery(2.8 to 4.5 V)Forward run prohibited(Prohibited when OFF)Servo alarm output(OFF for an alarm)Photocoupler outputMax. operating voltage: 30 VDCMax. output current: 50 mA DC∗2Encoder outputpulse phase AEncoder outputpulse phase BEncoder outputpulse phase CApplicable line receiver:SN75ALS175 or MC3486manufactured by TexasInstruments or the equivalentConnect shield toconnector shell.ConnectorshellSO1+SO1-/SO2+/SO2-/SO3+ALM+ALM-252627283132+24VIN+24 V 3.3 kΩ474244434546/SI0P-OTN-OT/DECGeneral-purpose/SI6General-purpose/SI5General-purpose/SI4General-purposeBAT+BAT-40212241/SO3-Multi-winding drive unit2930∗1∗3PBOPCO/PBOPAO/PAO/PCO193334353620FGCN1∗4ࠉࠉࠉࠉࠉࠉ∗4ࠉࠉࠉࠉࠉࠉ∗4ࠉࠉࠉࠉࠉࠉ+-1, 2, 6, 10PL1EXT1/EXT1+15 V378SGPL2EXT2/EXT2131112PL3EXT3/EXT3181514MECHA
