u Control Circuit Terminal Block FunctionsDrive parameters determine which functions apply to the multi-function digital inputs (S1 toS5), and multi-function digital outputs (MA, MB). The default is called out next to eachterminal in Figure 3.10.WARNING! Sudden Movement Hazard. Always check the operation and wiring of control circuits after beingwired. Operating a drive with untested control circuits could result in death or serious injury.WARNING! Confirm the drive I/O signals and external sequence before starting test run. Failure to complymay result in death or serious injury.NOTICE: Do not switch an input contactor more often than once every 30 minutes. Improper equipmentsequencing could shorten useful life of the drive electrolytic capacitors and circuit relays. Normally the driveI/O should be used to stop and start the motor.n Input TerminalsTable 3.6 Control Circuit Input TerminalsType No. Terminal Name (Function) Function (Signal Level) Default SettingMulti-FunctionDigitalInputsS1 Multi-function input 1 (Closed: Forwardrun, Open: Stop)24 Vdc, 8 mANote: Drive preset to sinking mode.
