Position measuring system
Description
One measuring system must be used for each axis as a piston rod position sensor.
SINAMICS HLA can simultaneously evaluate a maximum of 3 measuring systems. The
velocity control always operates with the first measuring system.
Possible connection configurations
● Using the integrated interface
– Incremental encoder (TTL) with (A, B and R track)
– Absolute encoder (SSI)
Measurement evaluation without incremental track is permitted.
● Using DRIVE-CLiQ encoders
– SMC30
– TTL
– SMC/SME20
Encoder assignment
You can find a description of the encoder assignment in Chapter "Configuration - Encoder
assignment (Page 64)".
Encoder configuration
You can find a description of the encoder configuration in Chapter "Configuration - encoder 1
... 3 (Page 66)".
