Setting up Compax3 C3F_T40
100 192-121102 N04 June 2008
Before the activation, please notice the following:
Correct connection of the pressure sensors to the controller.
By approaching the end limits and simultaneously monitoring the pressure
values (Status values pressure of main or auxiliary axis pa, pb, pT and p0)
it is possible to conclude if the pressure sensors are correctly assigned.
A = yclinder at limit A
B = cylinder at limit B
1 = valve position
The pressure signals should be well filtered (smooth). (Optimization Analog
input InX Filter)
If those conditions are fulfilled, the pressure compensation can be activated under
(Optimization Output Chain PressureCompensation).
b) characteristics compensation
The control behavior of valves with bent characteristic lines or overlap can be
considerably improved if the valve characteristics are stored in the controller and
are used for the compensation. The characteristic is integrated into the resepective
valve data via the C3HydraulicsManager and is loaded into the controller via the
C3ServoManager. The activation of the characteristic line is made via optimization
Output Chain Characterisitic Flow.
If the valve characteristic line is activated, the behavior between control signal and
speed should be mainly linear.
(Doubling of the setpoint speed Doubling of the resulting speed in the open
control loop).
c) Deadband compensation
If for valves with overlap or gap no adequate characteristics are available, they can
be optimized with the aid of the deadband compensation. The corresponding
values are set in (Optimization Output Chain Deadband ...).
