Wiring connection diagram
To prevent restart at fault occurrence, connect terminals RUN (SAFE2 signal) and SE to ter-
minals XS0 and XS1, because polarity of XS0 is positive, and polarity of XS1 is negative.
To prevent restart at fault occurrence, connect terminals RUN (SAFE2 signal) and SE to ter-
minals XS0 and XS1, which are the feedback input terminals of the safety relay module.
By setting Pr.190 to "81" (SAFE2 signal), terminal RUN is turned OFF at fault occurrence.
After the power-up, to reset the safety stop mode, press the START switch, and also press the
STF switch, then start the motor rotation. In the above wiring example, the motor rotation will not
occur in the event of reset of ‘safe-condition’ until STF is pressed.

NOTE
Changing the terminal assignment using Pr. 190, Pr. 192 or Pr. 197 may affect the other
functions. Make setting after confirming the function of each terminal.

CAUTION:
To prevent restart in case of recovering from input power loss of drive, 3-wired
connection for STF/STOP control is recommended. In case of 2-wire connection and
using latching type switch to short between STF and PC for starting, ensure the
compliance with safety requirement for the restarting when the drive recover from
input power loss.
