6. Control signal
6.1 Malfunction output
(1) Laser malfunction: When the laser does not emit a beam or exceeds the safety class 1.
(2) Motor malfunction: When rotation speed of the motor is not within 1,200 rpm
Sensor’s outputs are switch to OFF state, laser is turned OFF and motor is stopped on malfunction
detection. Check the error code via Ethernet. Error details and troubleshooting measure are shown in
Table meaning and handling methods for each error code can be found in Section 7.
6.2 Synchronization output
Sensor outputs a 1 ms pulse in every scan which is synchronized with the scanning. The timing of the
synchronization signal is shown in the figure below.
Synchronization
signal
During malfunction, synchronization output is OFF.
6.3 Synchronization master output
It is a reference clock signal for synchronizing the motor rotation.
The clock signal cycle is 50 ms and the period during which the output is ON (low level) is 12.5 ms
(Duty: 25%).
Signal is generated just after turning on the power supply of the sensor and it is continued even in the
failed state. Refer section 6.5 and 6.6 for further details.
6.4 Synchronization input
It is a reference clock signal received from the master sensor for synchronizing the motor rotation.
Motor rotation of the slave sensor is controlled to synchronize with the master sensor. Synchronization
is performed with the falling edge of the clock signal. Refer section 6.5 and 6.6 for further details.
