5.6 Encoder and Sync Switch Installation
Connecting One
Encoder to More Robots
One encoder can be used to control several robots. In this situation, power for the
encoder may be supplied by an external power supply, or by the robots.
Figure 41 Connecting one encoder to more robots
If the power supply is taken from the robot, the supply must be connected to all the
robots to make sure that the encoder will be operational even if one robot is
switched ‘off’. When supplying power from the robots in this way, it is important
that a diode is installed for each robot to prevent power from one of the robots
which is ‘on’ to be fed to a robot which is ‘off’.
If an external supply is used, the internal supply must not be connected.
