A connector (receptacle). Plug a USB memory
device into this connector to copy parameter
settings or use the trace function.
Mini B connector (receptacle). By connecting
the inverter to a personal computer via this
connector, FR Configurator2 installed on the
computer can be used for setting the inverter, or
monitoring or testing the inverter operation.
Terminal function description
Use terminals S1 and S2 to receive the safety stop signal input
from the safety relay module. Terminals S1 and S2 can be used
at a time (dual channel).
The Inverter judges the condition of the internal safety circuit from
the status (shorted/opened) between terminals S1 and SIC, or
between S2 and SIC. When the status is opened, the inverter
output is shut off.
In the initial status, terminal S1 and S2 are shorted with terminal
PC by shorting wires. Terminal SIC is shorted with terminal SD.
Remove the shorting wires and connect the safety relay module
when using the safety stop function.
Common terminal for terminals S1 and S2.
The output status varies depending on the input status of the
safety stop signals.
The output is in HIGH state during occurrence of the internal
safety circuit failure. The output is in LOW state otherwise.
(The open collector transistor is ON (conductive) in LOW state.
The transistor is OFF (not conductive) in HIGH state.)
Refer to the Safety Stop Function Instruction Manual if the output
becomes in HIGH state even though both terminals S1 and S2
are open. (Contact your sales representative for this manual.)
Common terminal for terminal So (SO).
