03.06
p9517 SI motion, linear scale, grid division
Sets the grid division for a linear motor encoder
Units: Default value:
nm 10 000
Grid spacing of the linear motor encoder (this only applies to linear motor encod-
ers). Corresponds to p0407.
p9518 SI motion, encoder pulses per revolution
Sets the number of encoder pulses per revolution for rotary motor encoders
Units: Default value:
-
2048
Number of pulses per encoder revolution for motor encoders (only applies to rotary
motor encoders). Corresponds to p0408.
p9519 SI motion, fine resolution G1_XIST1
Sets the fine resolution for G1_XIST1 in bits
Units: Default value:
-
11
The following applies to safety-relevant functions that have not been enabled (p9501 = 0):
when booting, p9519 is automatically set the same as p0418.
The following applies to safety-relevant functions that have been enabled (p9501 > 0):
p9519 is checked to ensure that it coincides with p0418.
Sets the fine resolution in bits of incremental position actual values for the PROFI-
BUS 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 16 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
Sets the ratio between the encoder and load in mm/rev for a linear
axis with rotary encoder
Units: Default value:
mm/rev 10
