Encoders with a DRIVE-CLiQ interface
Encoder evaluation units with DRIVE-CLiQ interface are available in the following versions:
● Sensor Module Cabinet-Mounted (SMCx) for rail mounting
● Sensor Module External (SMEx) to be incorporated in the feeder cable
● Sensor Module Integrated (SMI), mounted on the motor
● DRIVE-CLiQ Module Integrated (DQI) integrated in the motor
A temperature sensor at the DRIVE-CLiQ encoder to detect the motor temperature is
connected in the factory.
Support with STARTER version
The STARTER commissioning tool supports encoders with DRIVE-CLiQ interface. Additional
order numbers (MLFBs) are available for the corresponding DRIVE-CLiQ motors in the
encoder overview.
The motor order number is used for an SMI or DQI motor.
When configuring a motor with DRIVE-CLiQ interface, a distinction is not made between SMI
motors and DQI motors.
If you replace a motor with encoder and external DRIVE-CLiQ interface by an SMI motor or
DQI motor, then you must appropriately reparameterize the SMI/DQI motor.
The functional behavior differs for the following encoder changes:
● If the encoders differ due to the measurement principle and the resolution.
● If the encoders are used in applications where the evaluation requires a zero mark (for
● If an encoder is to be used on an axis with SINAMICS Safety Integrated Extended
A new commissioning test and, if necessary, new configuration must be carried out for
activated SINAMICS Safety Integrated Extended Functions or SINUMERIK Safety
Integrated.

example for referencing purposes). The encoder with integrated DRIVE-CLiQ interface
does not supply a separate zero mark, as it involves an absolute encoder. So in these
applications (and/or in the superimposed controls) the changed behavior must be
selected.
Functions or SINUMERIK Safety Integrated, because a lower position accuracy (SOS
Safe Operating Stop) and a lower maximum velocity (SLS Safely Limited Speed) is
obtained as a result of the lower resolution of the redundant position value (POS2).
