Enabling the drive via the PLC interface
By loading the SDB for the SINAMICS HLA, the analog drives are handled in the
same way as digital drives. Set the enable signals via the PLC interface.

Analog spindles on the SINUMERIK 828D

Supplementary conditions
Connection for encoder actual values
The precondition for connecting a spindle actual value encoder is an axis with
digital drive that is only equipped with one encoder. As the second encoder, a
Sensor Module, e.g. a SMC30, is connected to the Motor Module or to the
SINAMICS HLA module.
If no DRIVE-CLiQ connections are free, you can use a DMC20 or DME20 actual
value hub.
The Sensor Module is connected to the directly mounted spindle actual value
encoder. The PROFIdrive telegram of the digital drive must be configured for 2
encoder actual values. Depending on MD11240
($MN_PROFIBUS_SDB_NUMBER), the standard system data blocks of
SINUMERIK 828D support Siemens telegram 166 or Siemens telegram 136.
Functional restrictions
•
There is no setpoint telegram for the analog spindle; this means that the
functionality based on the setpoint telegram is not available, e.g. DSC and
torque feedforward control.
•
The driver software simulates the "Drive ready" signal as being set.
•
As it is not possible to access the drive parameters, the associated
functionality is restricted (e.g. spindle utilization display and automatic speed
and position controller optimization). The missing values are displayed in gray
in the "Service Overview" screenform in column Analog Spindle and the
following message is displayed: "This axis is not affected"

Connection X252 for spindle setpoints
Connect the analog spindle to interface X252 of the PPU. Depending on the
operating mode of the analog spindle, the following signals are output:
