5. Control signal
5.1 Malfunction Output
(1) Laser malfunction : When laser emission is not possible or laser power has exceeded the safety class 1.
(2) Motor malfunction : When motor rotation inside the sensor is unstable. When a malfunction occurs, the UGM-50LXP
switches the malfunction output to OFF (Low level), and then stops laser emission and motor rotation. You can check the
error code using communication protocol SCIP. Refer to troubleshooting table in section 6 for error details.
5.2 Synchronization output
The UGM-50LXP outputs a pulse of 1ms every one scan for synchronizing with the scanning.
The timing of the synchronization signal is shown in the figure below.
* Scan speed 20ms (In normal mode)

5.3 Synchronization master output
This is a reference clock signal for synchronizing motor rotation of each sensor.
The UGM-50LXP outputs the clock signal with cycle of 20ms and an output-OFF period (Low level) of 5ms (Duty25%).
Synchronization master output is continued even in the malfunction state.
