Main circuit
The switch for switching which of sink or source the digital input terminals DI1 to
DI7 are to be used for. (Factory default setting is SINK side)
The switch for switching the input type of terminal AI2. (Factory default setting is AII
side)
When set to the AII side, input becomes analog current input.
When set to the AIV side, input becomes analog voltage input.
The switch for switching the output type of terminal AO. (Factory default setting is
AOV side)
When set to the AOI side, output becomes analog current output.
When set to the AOV side, output becomes analog voltage output.
When set to the PO side, output becomes pulse output.
The switch for switching ON/OFF the RS-485 terminal on the control circuit termi-
nal block. When ON, the terminal is connected to the built-in 110-Ω terminating re-
sistor. (Factory default setting is OFF side)
Turn this switch OFF to use the safety function. Before you turn ON/OFF this
switch, be sure to turn off the power supply. For details, refer to 7-6 Safety Function
on page 7-69. (Factory default setting is ON side (safety function disabled))
The Micro-B type USB connector for connecting a computer.
Use this connector to connect the inverter to the Inverter/Servo support tool Sys-
mac Studio.
The terminal block for connecting various digital/analog I/O devices used for inver-
ter control.
The terminal block for connecting the safety input signal.
The SPDT contact terminal block for relay output.
The terminal block for connecting the main power supply for the inverter, outputs to
the motor, braking resistor, etc.
