Section 10 Connection of Conveyor Synchronization Signal Cable (CONV)
(Option)
The TSL3000E/TSL3100E has optional encoder input points for two-channel
conveyor synchronization.
Use encoders provided with A- and B-phase signals having 90° phase and the
output circuit having RS-422 differential output (line driver). To connect the
encoder signal cables, use the connectors [PCR-E20FS+ (connector), PCR-V20LB
(hood)] supplied with the robot controller.
It is requested that shielded twisted-pair cables be used as the conveyor
synchronization signal cables and that they be connected in pairs as shown below.
Note that a wrong connection method degrades the noise resistance, causing a
robot controller malfunction.
See the instruction manual "CONVEYOR SYNCHRONIZATION FUNCTION" for
further information.
