Commissioning The Encoders; Commissioning Or Modifying Encoders With The Drive Wizard - Siemens SINUMERIK 828D Manual

3 Commissioning
The examples above apply to a motor with a rated speed of 6000 rpm and an
encoder with 1024 pulses per revolution. If, for example, you use a motor with
rated speed 3000 rpm with an identical encoder, you must halve the value of
parameter p1475.
With parameter p1475 (loop gain), you can calibrate the tachometer of an axis in
very small steps.
If you increase the p1475 value, you can reduce the servo gain and thus the
calculated servo gain factor.
You can calibrate the axis offset with parameter P1832 (offset compensation).
If the analog converter is not operational and the SINAMICS HLA is in closed-loop
control, a traversing command results in alarm "207900 Velocity control output
limited". This alarm is suppressed when the commissioning files are loaded. This is
because a 1-BICO interconnection is implemented in parameter p2144 (motor
blocking monitoring enabled). As a result, alarm "25030 Alarm limit of actual
velocity" is displayed instead.
3.2.5

Commissioning the encoders

When the factory settings are loaded, the topology is also determined.
As soon as the commissioning files for the linear and rotary axes have been
loaded, a rotary TTL encoder with 1024 pulses/revolution is configured on the
SMC30 at ports X131 and X132.
For rotary encoders, you must additionally set parameter p4613 (cylinder path per
encoder revolution).
If you are using an encoder that is evaluated by a sensor module (SMC or SME)
with DRIVE-CLiQ connection or that has its own DRIVE CliQ connection, you must
insert that encoder in X202 for the 1st HLA axis and in X203 for the 2nd HLA axis.
Use the drive wizard as you would for a purely electric SINAMICS drive.

Press the "Change" softkey.
Acknowledge all subsequent screenforms by pressing the "Next step" softkey
because all necessary data has already been parameterized via the
commissioning file.
