SINUMERIK 840D/SIMODRIVE 611 digital Descr. of Functions HLA Module (FBHLA) – 04.00 Edition
Hydraulic linear drives (HLA) are adapted to the machine by means of machine
data.
For this purpose, softkey "Drive MD" is included in the machine data menu
along with the other softkeys

The following list shows the general steps to be taken to start up an HLA mod-
ule.
1. Select a valve
2. Enter cylinder data
3. Mounting/supply data
4. Measuring system data
5. Calculate controller data, save boot file, NCK reset.
6. MD 5475: OUTPUT_VOLTAGE_LIMIT output voltage limitation to low values
to check the control direction.
7. Approach reference point and adjust position;
Position adjustment if piston is in A position at end stop.
8. Adjust pressure sensors (MD 5550, MD 5551, MD 5552, MD 5553,
MD 5704, MD 5705, MD 5708). Adjust "manually" via these machine data or
automatically via MD 5650. Enter 1000 Hex in MD 5650. Data are reset to 0
after approximately 2 s and the sensors then adjusted. The sensors must be
unpressurized during adjustment.
9. Perform offset compensation with MD 5470.
Automatic offset compensation is possible via MD 5650 if 2000 Hex is en-
tered in MD 5650. Automatic offset compensation takes approximately 30 s
and functions only if the P and I components of the velocity controller are
active and all enabling signals are set (see Service Drive).
10. Reduce valve knee-point voltage in MD 5111 by 2...3% if necessary.
11. Area adaptation in MD 5462, set MD 5463 such that the control difference in
the positive and negative traversing directions is almost identical.
12. Friction compensation and force limitation
MD 5241=1000 Hex
MD 5241=2000 Hex
MD 5241=3000 Hex
