The positive direction of travel of the machine is defined by the user.
With adjustment of travel direction with setpoint MD 32100: AX_MOTION_DIR.

The setpoint limitation must be set to 10 V in the following MDs:
MD 5474: OUTPUT_VOLTAGE_POS_LIMIT
MD 5475: OUTPUT_VOLTAGE_NEG_LIMIT
3.9.2 Offset adjustment
Note
Only in combination with pressure sensing function.
Condition: Sensors are pressure-free!
Ideal: The pressure indicator should also display 0 bar at zero pressure.
Adjustment:
S MD 5650: Set DIAGNOSIS_CONTROL_FLAGS bit 12 (canceled automati-
cally after 2 s).
S Pressure sensor A: MD 5551: PRESSURE_SENS_A_OFFS is automatically
adjusted.
S Pressure sensor B: MD 5553: PRESSURE_SENS_B_OFFS is automatically
adjusted.
For unpressurized pressure sensors, the display must read approximately 0.0
bar for both pressures (MD 5704, MD 5705).
