Equivalent circuit of the output stage
NOTE
VCC
10
(5V) is a intern generated, isolated supply voltage.
NOTICE
Inductive loads can damage the output stages.
• Wire a protective diode antiparallel to the output.
3.4.10 Base jaw with a sensor port
The product has an integrated sensor port in each of the base jaws
which makes it easy to connect intelligent gripper fingers. The
sensor port makes the following interfaces available:
• UART (LVTTL levels)
• SPI (LVTTL levels)
• Analog input (0 to 2.5 V)
The sensor port supports the automatic configuration of the
connected fingers. To use this function, a configuration memory
must be integrated into the fingers. All of the intelligent fingers
offered by SCHUNK for this gripper (e.g. force measurement
finger) already have this memory integrated and are completely
configured, so that you just have to fit this finger to the product.
The fingers will then be automatically detected the next time the
system starts.
The sensor port supplies an operating voltage of 5 V ±10% at max.
200 mA. The supply voltage is protected against short circuits and
can be switched on and off from the gripper control system. A
short circuit in the supply voltage will trigger an error state which
must be acknowledged.
NOTE
The power supply from the sensor port is not suitable to supply
actuators.
