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 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.
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
SOC
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.)
