Note
Risk of encoder failures by encoder signal disturbances
Unfavorable material combinations generate static electricity between the belt pulley and the
belt. This electrostatic charge (several kV) can discharge via the motor shaft and the
encoder which leads to disturbance of the encoder signals (encoder error).
• Use an antistatic version of the belt (special conductive polyurethane mixture).
WARNING
Danger to life due to electric shock when disconnecting and connecting encoder cables
during operation
When disconnecting plug-in connections during operation, arcs can result in severe injury
or death.
• Only disconnect or connect the encoder cables to Siemens motors in a voltage-free
state if hot-plugging has not been specifically released. When using direct measuring
systems (third-party encoders), ask the manufacturer whether hot-plugging is permitted.
NOTICE
Damage when connecting an impermissible number of encoder systems
Damage results when more than the maximum permissible number of encoder systems are
connected to a Sensor Module.
• Only connect one encoder system to a Sensor Module.
Note
Reduced interference immunity through equalization currents via the electronic ground
Make sure there is no electrical connection between the encoder system housing and the
signal lines and the sensor system electronics.
If this is not carefully observed, under certain circumstances the system will not be able to
reach the required interference immunity level (there is then a danger of equalization
currents flowing through the electronics ground).
NOTICE
Damage through the use of incorrect DRIVE-CLiQ cables
Damage or malfunctions can occur on the devices or system when incorrect or unreleased
DRIVE-CLiQ cables are used.
• Only use suitable DRIVE-CLiQ cables that have been released by Siemens for the
respective application.
