7.2 Continuous controllers
At Xsh1 = Xsh2 = 0 the Xp1 is uninterrupted. At Y0 = 0 the Xp1 is uninterrupted and Xsh2 is ineffective.
The static characteristic is the same as that of the two-step controller.
Static functioning of a continuous controller
In a continuous controller with position feedback the actual flow of the control current can be
measured and displayed with INP6. Yp is again not included in the control process.
The maximum and minimum output currents are adjustable:
y
min
= 0...100 % (min. current)
y
max
-y + 10 % (max. current)
The operating point can be set at Y0 = 0..100 %.
Setting aids for optimizing control
