SIMODRIVE 611 universal Description of Functions (FBU) – 04.05 Edition
Encoder x position actual value 2 ––> Additional position actual value
Different values are entered in Gx_XIST2 depending on the function
(refer to Fig. 5-17).
 Priorities for Gx_XIST2
The following priorities should be considered for values in
Gx_XIST2:
Gx_ZSW.14 = 1?
Gx_XIST2

 Resolution: Encoder pulses  2
n
n: Fine resolution
Number of bits for the internal multiplication
The fine resolution is defined via P1043/P1045 or P1042/P1044 for
the ”requested value” or the ”absolute value” in Gx_XIST2.
P1043 Encoder 1, fine resolution, absolute track G1_XIST2
P1045 Encoder 2, fine resolution, absolute track G2_XIST2
P1042 Encoder 1, fine resolution G1_XIST1
P1044 Encoder 2 fine resolution G2_XIST1
