5.4 Synchronization input
In a multiple connection of UGM-50LXP, you can synchronize with motor rotation inside each sensor. By connecting the
synchronization input terminal of the slave to both synchronization master output terminal and the synchronization input
terminal of the master, you can synchronize the motor rotation of the slave with the motor rotation of the master. Synchro-
nization is performed on the falling edge of the clock signal.
5.5 Example of connection between multiple sensors for synchronization of motor rotation
UGM-50LXP
UGM-50LXP
As shown in the figure above, it is possible to synchronize the motor rotation of the slave with the motor rotation of the
master according to the shifted scanning time of each slave sensor by setting phases of each slave sensor.
You can confirm and configure phases using the application software.
5.6 Timing chart of synchronization input/output
・ When the synchronization master output of the master is not connected to the synchronization input of the slave, the
synchronization output terminals of both the master and the slave sensors continue to output pulse signals accordingly
with a cycle of 20ms and low of 1ms.
