3.7 Control Circuit Wiringu Control Circuit Terminal Block FunctionsDrive parameters determine which functions apply to the multi-function digital inputs (S1 to S8), multi-function digital outputs(M1 to M6), multi-function analog inputs (A1 to A3), and multi-function analog monitor output (FM, AM). The default settingis listed next to each terminal in Figure 3.1 on page 81.WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after being wired. Operating a drive withuntested control circuits could result in death or serious injury.WARNING! Sudden Movement Hazard. Confirm the drive I/O signals and external sequence before starting test run. Setting parameterA1-06 may change the I/O terminal function automatically from the factory setting. Refer to Application Selection on page 134. Failureto comply may result in death or serious injury.n Input TerminalsTable 3.7 lists the input terminals on the drive. Text in parenthesis indicates the default setting for each multi-function input.Table 3.7 Control Circuit Input TerminalsType No. Terminal Name (Function) Function (Signal Level) Default Setting PageMulti-FunctionDigital InputsS1 Multi-function input 1(Closed: Forward run, Open: Stop)• Photocoupler• 24 Vdc, 8 mA• Refer to Sinking/Sourcing Mode for Digital Inputs on page110.288S2 Multi-function input 2(Closed: Reverse run, Open: Stop)S3 Multi-function input 3(External fault, N.O.)S4 Multi-function input 4(Fault reset)S5 Multi-function input 5(Multi-step speed reference 1)S6 Multi-function input 6(Multi-step speed reference 2)S7 Multi-function input 7(Jog reference)S8 Multi-function input 8(Baseblock command (N.O.))SC Multi-function input common Multi-function input commonSP Digital input power supply +24 Vdc 24 Vdc power supply for digital inputs, 150 mA max (only whennot using digital input option DI-A3)NOTICE: Do not jumper or short terminals SP and SN.Failure to comply will damage the drive.110SN Digital input power supply 0 V 110Safe DisableInputsH1 Safe Disable input 1 • 24 Vdc, 8 mA• One or both open: Output disabled• Both closed: Normal operation• Internal impedance: 3.3 kΩ• Off time of at least 1 ms• Disconnect the wire jumpers shorting terminals H1, H2, and HCto use the Safe Disable inputs.
