Fig.6 Safety system example 2 – STOP synchronous with emergency stop button and fault
For safety stop, configure the wiring as shown in Fig.6 above.
Note: the above wiring is configured to prevent restart in case of a fault.
XS0 should be connected to RUN terminal and XS1 should be connected to SE, because polarity of XS0 is
positive, XS1 is negative.
The parameter No.190 (RUN terminal function selection) must be set to '81'. This setting makes the RUN
output to turn off in case of failure.
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 Fig.6, wired example2, in the event of reset of 'safe-condition' the motor rotation will not occur
until STF is pressed.
(for normal 'non-safety' STF/STOP function, please refer to your drive's User Manual)
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 SD/PC for starting,
ensure the compliance with safety requirement for the restarting when the drive recover from input power
loss.
