Semiconductor input
Set standstill detection
} Turn the potentiometer to the left-hand stop (default setting)
} Set standstill detection
– At motor standstill, the LEDs "CH.1 IN" and "CH.2 IN" must light up. If the LEDs do
not light in the default setting, turn the potentiometer gradually to the right until the
LEDs "CH.1 IN" and "CH.2 IN” light up.
– If the simultaneity requirement is met, the "OUTPUT” LED will also light up. Safety
contacts 13-14 and 23-24 are closed, auxiliary contact 41-42 is open, there is a
High signal at the semiconductor output Y32.
– If the simultaneity requirement is exceeded, the "FAULT" LED will light up. Safety
contacts 13-14 and 23-24 are open, auxiliary contact 41-42 is closed, a low signal is
present at semiconductor output Y32. Reset the error by a pulse (High- Low- signal)
at the reset input.
} Test standstill detection
– Close the feedback loop, start up the motor and then switch it off again. As soon as
the motor is at standstill, the LEDs "CH.1 IN", "CH.2 IN" and "OUTPUT" light up.
Safety contacts 13-14 and 23-24 are closed, auxiliary contact 41-42 is open, there
is a High signal at the semiconductor output Y32.
