NOTICE
Damage when connecting an impermissible number of encoder systems
If more than the maximum permissible number of encoder systems are connected to a
Sensor Module, this will cause damage.
• Only connect one encoder system per Sensor Module.
NOTICE
Damage caused by the use of incorrect DRIVE-CLiQ cables
The use of incorrect or not released DRIVE-CLiQ cables can cause damage or functional
faults to devices or the system.
• Use only appropriate DRIVE-CLiQ cables that have been approved by Siemens for the
Note
Diminished level of interference immunity due to equalizing currents via the electronics
ground
Ensure that there is no electrical connection between the encoder system housing and the
signal cables, or the encoder system electronics. If this is not carefully observed, the system
may not be able to reach the required interference immunity level. (There is then a danger of
equalization currents flowing through the electronics ground.)
Note
Function equipotential bonding for distributed DRIVE-CLiQ nodes
Integrate all of the components that are connected via DRIVE-CLiQ into the function
equipotential bonding concept. The connection should be preferably established by mounting
on metallic bright machine and plant components that are connected with one another using
an equipotential bonding conductor.
Alternatively, you can establish equipotential bonding using a conductor (min. 6 mm²), which
as far as possible, is routed parallel to the DRIVE-CLiQ cable. This involves all distributed
DRIVE-CLiQ nodes, for example, SMCxx.
Note
Functional faults caused by dirty DRIVE-CLiQ interfaces
Malfunctions can occur in the system due to use of dirty DRIVE-CLiQ interfaces.
• Close any unused DRIVE-CLiQ interfaces with the supplied cover plates.
