Encoder systems without a DRIVE-CLiQ interface
For motors without an integrated DRIVE-CLiQ interface, the analog encoder signal is first
converted to a digital signal in the drive system. For these motors, the encoder signals for
SINAMICS S110 / S120 must be transferred via Sensor Modules.
NOTICE
Damage to components that are sensitive to electrostatic discharge
The contacts of the connector plug have direct contact to components that can be
damaged/destroyed by electrostatic discharge (ESDs).
• Do not touch the connections directly even with tools that could be electrostatically
charged.
2.6.4.1 Overview of the encoders that can be deployed
NOTICE
Destruction of the encoder when incorrectly handling ESD parts and components
Encoders are ESD components.
• Carefully comply with the regulations for handling parts and components that can be
destroyed by electrostatic discharge. See
Equipment damage due to electric fields or
electrostatic discharge (Page 16)
The following encoders can be used with the 1FK7.
