A connector (receptacle).
Plug a USB memory device into this
connector to copy parameter settings or use
the trace function.
Mini B connector (receptacle).
The inverter can be connected to a personal
computer.
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).
