Encoder

Motors with DRIVE-CLiQ interface are designed to operate with the SINAMICS converter system.
Signal transmission to the converter is performed digitally.
The motors have an electronic rating plate that simplifies commissioning and diagnostics.
The motor and encoder system are automatically identified and all motor parameters are
automatically set.
You will find further information in the relevant SINAMICS manual.
NOTICE
Damage to electrostatic sensitive devices
The contacts of the DRIVE-CLiQ interface have direct contact with components that can be
destroyed by electrostatic discharge (ESDS).
• Avoid touching the terminals directly with hands or tools. They may be electrostatically
The encoders are suitable for the extended safety functions.
