p2200
BI: Technology controller enable (factory setting: 0)
1 signal:
Technology controller is enabled.
r2294
CO: Technology controller output signal
To interconnect the main speed setpoint with the technology controller output, set
p1070 = 2294.
p2253
CI: Technology controller setpoint 1
(factory setting: 0)
Setpoint for the technology controller.
Example:
p2253 = 2224: The inverter interconnects the fixed setpoint p2201 with the setpoint
of the technology controller.
p2220 = 1: The fixed setpoint p2201 is selected.
p2264
CI: Technology controller actual value
(factory setting: 0)
Technology controller actual value.
p2257, p2258
Technology controller ramp-up time and ramp-down time (factory setting: 1 s)
p2274
Technology controller differentiation time constant T
d
(factory setting: 0.0 s)
The differentiation improves the rise time for very slow controlled variables, e.g. a
temperature control.
p2280
Technology controller proportional gain K
P
(factory setting: 1,0)
p2285
Technology controller integration time (integral time) T
d
(factory setting: 30 s)
