Example: Commissioning and replacement of a DRIVE-CLiQ encoder

The following describes commissioning and replacing an encoder using the DRIVE-CLiQ
encoder as an example.
Support by STARTER
The STARTER commissioning tool supports encoders with DRIVE-CLiQ interface. Additional
article numbers for the corresponding DRIVE-CLiQ motors are provided in the encoder
overview.
The motor article 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
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 higher-level controllers) the changed behavior must be
selected.
● If an encoder is to be used on an axis with SINAMICS Safety Integrated Extended
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).
A new commissioning test and, if necessary, new configuration must be carried out for
activated SINAMICS Safety Integrated Extended functions or SINUMERIK Safety Integrated.
