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.
Step 3 (define travel direction of machine)
Traverse with JOG key
(override approx. 10%)
Does cylinder move
in the set direction ?
yes

The setpoint limitation must be set in MD 5475: OUTPUT_VOLTAGE_LIMIT to
10 V.
Note
Only in combination with pressure sensing function.
Condition: Sensors are pressure-free!
Objective: The pressure display should be 0 at 0 pressure.
Adjustment:
S
MD 5650: Set DIAGNOSIS_CONTROL_FLAGS bit 12 (cancelled 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.
The display for the two pressures (MD 5704, MD 5705) should then show
about 0.0 bar.
no
MD 32100: Change AX_MOTION_DIR
