● Control Circuit Terminals Specifications Relay output Selection Features Analog output Logic input Logic output Analog input Short-circuit bar SYSDRIVE JX Series SYSDRIVE MX Series SYSDRIVE RX Series SYSDRIVE Option Overview of Inverter Selection ● Mode Selector RS-485 Communication/Operator Selector (S7) Select the mode according to the option connected to the communications connector. When using the 3G3AX-OP01 supplied with the Inverter, it is available regardless of the switch condition. Emergency shutoff selector (S8) Use this selector to enable the emergency shutoff input function.
* The multi-function input terminal 3 is switched to a terminal for emergency shutoff input, and the allocation of other multi-function input terminals is also changed automatically. Do not set to ON immoderately. For details, refer to "Emergency Shutoff Input Function".
