Sigma II User’s Manual Chapter 5: Parameter Settings and Functions5 - 265.2.4 Sequence I/O SignalsSequence I/O signals are used to control servo amplifier operation. Connect thesesignal terminals as required. Input Signal ConnectionsConnect the sequence input signals as shown below.Note: Provide a separate external I/O power supply; the servo amplifier does not have an internal 24Vpower supply.• External power supply specifications: 24V ±1 V DC , 50mA minimum.Yaskawa recommends using the same type of external power supply as that used for output circuits.The function allocation for sequence input signal circuits can be changed.See 5.3.3 Input Circuit Signal Allocation for more details.The external power supply input terminal is common to sequence input signals.Contact input signals: /S-ON (CN1-40)/P-CON (CN1-41)P-OT (CN1-42)N-OT (CN1-43)/ALM-RST (CN1-44)/P-CL (CN1-45)/N-CL (CN1-46)Input +24VIN CN1-47 External I/O Power Supply Input Speed/Torque Control,Position ControlI/O powersupplyCN1-47CN1-40CN1-41CN1-42CN1-43CN1-44CN1-45CN1-460V+ 24VServo AmplifierPhotocouplerHost controller +24VIN/S-ON/P-CONP-OTN-OT/ALM-RST/P-CL/N-CL3.3kΩServo amplifierI/O power supplyConnect an external I/O power supply+24V+24VinCN1-47
