Functional description of the slide switches is explained in Table 2.2-31 Functional Description of Slide switches.
Table 2.2-31 Functional Description of Slide switches
Switch symbol Functional description
SW1 <Switch to change sink/source setting of digital input terminals>
• This switch determines the type of input (sink or source) to use for digital input terminals [X1] to [X5],
FWD, and REV.
SW2 <Switch to change the RS-485 communication port 1 terminating resistor (RS-485 communication port (on
the control PCB))>
• Move the switch to the ON side when RS-485 communication is used and the inverter is located at
either end of the communication network.
SW3
SW4
<Switch to change terminal [C1] input setting to current/voltage/PTC thermistor>
This switch changes the input type for terminal [C1].
Input type
SW3 SW4 E59 H26
Current input (factory default) C1 side AI side 0 0
Voltage input V2 side AI side 1 0
PTC thermistor input C1 side PTC side 0 1
SW5 <Switch to change terminal [FM] output setting to current/voltage/pulse>
This switch changes the output type for terminal [FM]. When operating this switch, also change function
code F29.
Output type
SW5 F29
Current output FMI side 1 or 2
Voltage output (factory default) FMV side 0
Pulse output FMP side 3
SW6 <Switch to change the RS-485 communication port 2 terminating resistor (RS-485 communication port (on
the terminal board))>
・ Used for the RS-485/CANopen communication. Move the switch to the ON position when the inverter is
located at either end of the communication network.
SW7 <Switch to change terminal [FM2] output setting to voltage/current> The terminal is used only on the model
with the destination code -C.
This switch changes the output type for terminal [FM2]. When operating this switch, also change function
code F32.
Output type
SW7 F32
Voltage output FMV2 side 0
Current output FMI2 side 1 or 2
Exercise caution as expected operation may not result if the setting above is not conducted accurately.
