NOTE
The transducer system integrated in the product acts as a pseudo
absolute-value transducer in conjunction with the position
maintenance brake. Therefore, under certain conditions,
referencing may be omitted after a restart, provided that the base
jaws can move freely and have not been moved manually before.
To ensure a reliable process sequence, SCHUNK recommends
carrying out a reference run after each system restart.
6.1 Systemintegration
For communication between PLC and product, SCHUNK provides
the following two protocols:
• SCHUNK Drive Protocol (SDP)
– Recommended for PROFIBUS by SCHUNK.
– Not available with CAN bus.
• SCHUNK Motion Protocol (SMP)
– Available for CAN bus and PROFIBUS.
6.1.1 SCHUNK Drive Protocol (SDP)
If products are connected to the PLC via PROFIBUS, the "SDP"
protocol is available.
For more information, see software manual "SCHUNK Drive
Protocol (SDP)".
6.1.2 SCHUNK Motion protocol (SMP)
If products are connected to the SPS via PROFIBUS or PROFINET,
the "SMP" protocol is available.
For PROFIBUS, SCHUNK recommends using the "SDP" protocol.
For more information, see software manual "SCHUNK Motion
Protocol (SMP)".
