Universal Robots UR30 - Tool Communication I;O

Caution
CAUTION
Analog Inputs are not protected against over voltage in current mode.
Exceeding the limit in the electrical specification can cause permanent
damage to the input.

Analog Inputs,
Non-
differential
This example shows an analog sensor connection with a non-differential output. The
sensor output can be either current or voltage, as long as the input mode of that Analog
Input is set to the same on the I/O tab.
Note: You can check that a sensor with voltage output can drive the internal resistance of
the tool, or the measurement might be invalid.

This example shows an analog sensor connection with a differential output. Connecting the
negative output part to GND (0V), works in the same way as a non-differential sensor.

8.10.11. Tool Communication I/O
Description
•
Signal requests The RS485 signals use internal fail-safe biasing. If the attached
device does not support this fail-safe, signal biasing must either be done in the
attached tool, or added externally by adding pull-up resistors to RS485+ and pull-
down to RS485-.
•
Latency The latency of messages sent via the tool connector ranges from 2ms to
4ms, from the time the message is written on the PC to the start of the message on
the RS485. A buffer stores data sent to the tool connector until the line goes idle.
Once 1000 bytes of data have been received, the message is written on the
device.
