Safety stop function
The terminals related to the safety stop function are shown below. For the rated specification of each
terminal refer to Tab. 3-9.
햲
In the initial status, terminal S1 and S2 are shorted with terminal PC by shortening wire. Remove
the shortening wire and connect the safety relay module when using the safety stop function.
햳
In the initial setting, output frequency detection (FU signal) is assigned to terminal FU. Set "80" to
Pr. 191 "FU terminal function selection" to assign SAFE signal. The function can be assigned to
other terminals by setting "80" (positive logic) or "180" (negative logic) to any of Pr. 190 to Pr. 192
(Output terminal function selection).
햴
In the initial setting, inverter running (RUN signal) is assigned to terminal RUN. Set "81" to Pr. 190
"RUN terminal function selection" to assign SAFE2 signal. The function can be assigned to other
terminals by setting "81" (positive logic) or "181" (negative logic) to any of Pr. 190 to Pr. 192 (Output
terminal function selection).
햵
At an internal safety circuit failure, one of E.SAF, E.6, E.7, and E.CPU is displayed on the operation
panel.
Terminal
Description
S1
햲
For input of safety stop channel 1.
Between S1 and PC / S2 and PC
Open: In safety stop state.
Short: Other than safety stop state.
S2
햲
For input of safety stop channel 2.
PC
햲
Common terminal for terminal S1 and S2.

FU
햳
SAFE
signal
Outputs the safety stop status
The signal is output when inverter output is shut off
due to the safety stop function.
OFF: Drive enabled or drive stop
(at an internal safety circuit failure
햵
)
ON: Drive stop
(no internal safety circuit failure
햵
)
RUN
햴
SAFE2
signal
Outputs when an alarm or failure is detected.
The signal is output when no internal safety circuit
failure
햵
exists.
OFF: Internal safety circuit failure
햵
ON: No internal safety circuit failure
햵
SE
Common terminal for open collector outputs
(terminal RUN and FU)

Tab. 3-14:
Safety stop function terminals
NOTES
Hold the ON or OFF status for 2 ms or longer to input signal to terminal S1 or S2. Signal input
shorter than 2ms is not recognized.
Use SAFE signal to monitor safety stop status. SAFE signal cannot be used as safety stop input sig-
nal to other devices (other than the safety relay module).
SAFE 2 signal can only be used to output an alarm or to prevent restart of an inverter. The signal
cannot be used as safety stop input signal to other devices.
