SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
References: Bosch AKY 013/2
The HLA module supports Bosch servo solenoid valves with integrated (OBE)
electronics, for which technical data are stored in the software of the module, as
well as valves supplied by other manufacturers. The drive is parameterized au-
tomatically when the order number is entered. The following table shows an
overview of the servo solenoid valves supplied by Bosch.
