SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Note
If signals which do not conform to this specification are used, problems such as
speed ripple, positioning inaccuracy or other malfunctions may be encoun-
tered.
When the encoder is parameterized, one of the options "Incremental" or "Abso-
lute" (EnDat interface) must be selected in menu display "Measuring system
data for HLA".
The purpose of these options is to set the following drive machine data:
S
MD 5011: ACTUAL_VALUE_CONFIG (actual-value sensing configuration)
S
MD 5024: DIVISION_LIN_SCALE (linear scale graduations).
