Controller channels
Number
4
Controller type
Two-state controllers
Three-state controllers
Continuous controller
Coarse/fine controller
Modulating controllers
Continuous controller with position controller
Controller structure
P, PI, PD, PID
Controller outputs
For each controller channel, 2 outputs configurable as: pulse
length output, pulse frequency output,
(maximal 240 pulses per minute), continuous output
Disturbance feedforward con-
trol
multiplicative and/or additive
a
a
Ena. variable disturbance permits consideration of influencing variables in the process
environment beyond the actual value alone. This keeps the controller behavior stable, even when
fluctuations in such ambient conditions occur.
Self-optimization
Step response method
Sampling rate
250 ms
