6.5.3.2.1 Rotational direction
Danger of death, severe personal injury and/or material damage due to a
jump in the absolute value when the code sequence is changed!
 The internal calculation algorithm results in different absolute positions
for the counting direction settings backward and forward. Therefore,
after changing the rotational direction, verify the correct function by a
protected test run first. Under certain circumstances, the output position
must be adjusted via the preset function.

6.5.3.2.2 Scaling parameter
Risk of physical injury and material damage due to shifting of the zero
point when the measuring system is switched on again after positioning
in de-energized state!
If the scaling parameter settings listed below deviate from the default settings,
the zero point of the multi-turn measuring system may be lost if more than the
permissible revolutions are performed in the de-energized state!
 SIL2 – measuring system: Make sure that positioning operations in de-
energized state take place within 3200 revolutions on a multiturn measuring
system.
 SIL3 – measuring system: Make sure that positioning operations in de-
energized state take place within 320 revolutions on a multiturn measuring
system.
 If this cannot be ensured, the issued position must first be verified with the
desired mechanical position before the application can be started.
If the permissible revolutions have been exceeded, this fact is indicated by
a PROFINET diagnostic alarm of error type 8211
dec
when the measuring
system restarts. This fact is displayed in TR-Status1, Bit 7 Scaling
Error = 1 via the cyclic process input data. After positive verification, the
PROFINET diagnostic alarm bit and the Scaling Error bit can be
cleared by executing the preset adjustment function, see Chapter 6.5.4 on
Page 118.
The physical resolution of the measuring system can be changed using the scaling parameters. The
measuring system supports the gear function for rotary axes.
This means that the number of steps per revolution and the quotient of Revolutions numerator
/ Revolutions denominator can be a decimal number.
The output actual position value is offset by a zero-point correction, the set counting direction and the
entered gearbox parameter.
