control using the technology controller
● Analog inputs smoothing time constant: p0753 = 500 ms
● Technological unit: p0595 = 1 (%), reference variable: p0596 = 1
● Default setting of the technology controller:
– Enable: p2200 = 1
– Fixed value 1: p2201 = 50 %
– Fixed value 3: p2203 = 10 %
– Technology controller setpoint 1: p2253 = r2224 (active fixed value)
– Ramp-up/down time for setpoint: p2257 = p2258 = 30 s
– Upper and lower limits, actual value: p2267 = 120 %, p2268 = -10 %
– Actual value filter time constant: p2265 = 10 s
– Technology controller system deviation inversion: p2306 = 1
● "Flying restart" is enabled: p1200 = 1
● Automatic restart is active. After a power failure, the inverter automatically acknowledges possible
