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 PC, or between
S2 and PC. 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. 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 fault. 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 FR-E800 Instruction Manual (Functional Safety)
(BCN-A23488-000) when the signal is switched to HIGH
while both terminals S1 and S2 are open. (Contact your sales
representative for this manual.)
Terminal function description
Common terminal for the contact input terminal (sink logic).
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the source logic to avoid
malfunction by undesirable current.
Common terminal for the 24 VDC power supply (terminal
PC). Isolated from terminal 5.
Connect this terminal to the power supply common terminal
of a transistor output (open collector output) device, such as
a programmable controller, in the sink logic to avoid
malfunction by undesirable current.
Common terminal for safety stop input terminals
Common terminal for contact input terminal (source logic).
Common terminal for the frequency setting signal (terminal
2 or 4). Do not earth (ground).
Common terminal for terminal SO.
