Analogue input signals - signals from robot to
power source
General The analogue differential amplifier inputs on the interface ensure that the inter-
face is electrically isolated from the analogue outputs on the robot controller.
Each input on the interface has its own negative potential.
NOTE!
If the robot controller uses only a common GND for its analogue output signals,
the negative potentials, i.e. the inputs on the interface, must be linked together.
The analogue inputs described below are active at voltages of 0 - 10 V. If indivi-
dual analogue inputs are not assigned (for example for Arclength correction) the
values set at the power source will be used.
Available signals Descriptions of the following signals can be found in the document "Signal de-
scriptions for TPS/i interface".
