p9519 SI motion fine resolution G1_XIST1 (Control Unit)
Sets the fine resolution for G1_XIST1 in bits
The following applies to safety–related functions that have not been enabled
(p9501 = 0):
when booting, p9519 is automatically set the same as p0418.
The following applies to safety–related functions that have been enabled
(p9501 > 0):
p9519 is checked to ensure that it coincides with p0418.
Unit: Default value:
- 11
Sets the fine resolution in bits of incremental position actual values for the
PROFIBUS encoder interface. Corresponds to p0418.
Comments regarding minimum and maximum value:
S The minimum value is 2 so that the complete segment information is always
included in the position actual value and the check with the redundant coarse
position can always be made with the full 16–bit resolution.
S The maximum value is 18 so that at least 16 bits of coarse position information
are always included in the position actual value and the check with the redun-
dant coarse position can always be made with the full 16–bit resolution.
p9520 SI motion spindle pitch (Control Unit)
Sets the ratio between the encoder and load in mm/rev for a linear axis with
rotary encoder
Unit: Default value:
mm 10
p9521[0...7] SI motion, gearbox, encoder/load, denominator (Control Unit)
Sets the denominator for the gearbox between the encoder and load. The ac-
tual stage is selected using safety–related inputs (SGE).
Unit: Default value:
– 1
Denominator of the fraction "number of encoder revolutions/number of load revo-
lutions".
There are a total of 8 values (8 indices of p9521), whereby, the actual value is se-
lected using SGEs.
p9522[0...7] SI motion, gearbox, encoder/load, numerator (Control Unit)
Sets the numerator for the gearbox between the encoder and load. The actual
stage is selected using safety–related inputs (SGE).
Unit: Default value:
– 1
Numerator of the fraction "number of encoder revolutions/number of load revo-
lutions".
There are a total of 8 values (8 indices of p9522), whereby, the actual value is se-
lected using SGEs.
