Setting up Compax3 C3F_T40

Limit valve set value
In the optimization tree under output chain:
Upper limit of control signal (Object 2400.3) and lower limit of control signal
(Object 2400.4) must be set sensibly.
Take step 1 for all additional valves.
Tip:
In order to avoid a fast, uncontrolled movement of the drive during the setup, the
valve outputs should at first be limited!
Attention:
The drive does not reach its maximum power due to the limitation of the valve
outputs.
As soon as the drive is stably positioned in the control loop, the limitation can be
lifted.
Move drive controlledly
In the optimization window ⇒ setup field ⇒ setup.
Select "controlled movement" operating mode.
Energize drive (2).
Move the drive to both sides (3).
Does the axis move?
No:
Valve positive overlap? -> activate valve characteristic line or set deadband
compensation.
Check control value limitation -> increase control value limitation.
Control signal gain too small -> increase parameter control signal gain.

Tip:
Check, if the control signals to the valves (status values -> valve outputs -> output
signal0..3) change.
