The HLA module supports servo solenoid valves with on-board electronics
(OBE) supplied by Bosch Rexroth AG. The technical data for these valves and
valves supplied by other manufacturers is stored in the HLA module software.
The drive is parameterized automatically when the order number is entered.
The following table lists the various types of servo solenoid valve and HR (=
High Response) servo solenoid valves available from Bosch Rexroth AG.
For a complete list, please see Tables 2-4 to 2-10.
