SINUMERIK 840D/SIMODRIVE 611 digital, HLA Module (FBHLA) - 10.03 Edition
Hydraulic linear drives (HLA) are adapted to suit the machine using the machine
data.
In addition to the following soft keys:
S General MD
S Channel MD
S Axis MD
S Display MD
Softkey “Drive MD”.
The following list shows the general steps to be taken to start up an HLA mod-
ule.
1. Select a valve ³ Select a valve from the list
2. Enter cylinder data
3. Mounting/supply data
4. Measuring system data
5. Calculate controller data, save boot file, NCK reset.
6. MD 5474: OUTPUT_VOLTAGE_POS_LIMIT and
MD 5475: OUTPUT_VOLTAGE_NEG_LIMIT
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” using this machine data or
automatically via MD 5650. Enter 1000 Hex in MD 5650. The data is reset to
0 after approximately 2 s and the sensors are then adjusted. The sensors
must be unpressurized during adjustment.
9. Run offset compensation MD 5470.
Automatic offset compensation can be run 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. Force limitation and friction torque compensation, see Section 4.4.
