The system has corresponding limit alarm. Please check corresponding limit sensor point or
parameters.
If hard limit occurs, and the appearance of the sensor point doesn’t has any problem, enter the
diagnosis mode in manual mode and check the state of the input port in diagnosis mode. If the
state is valid, please eliminate in sequence. Pull out the input IO cable and check whether the sense
disappears. If yes, please check the circuit. If the problem still exists, the internal optocoupler is
broken. Please contact the supplier.
Emergency stop button of the handheld box interface is valid.
External emergency stop 2 input is valid; check whether IO assignment has conflict or
interference.
Search for corresponding function ports in IO configuration, and then check in input diagnosis.
