Additional settings:
• Temperature control using the technology controller
• Analog inputs smoothing time constant: p0753 = 100 ms
• Technological unit: p0595 = 1 (%), reference variable: p0596 = 1
• Default setting of the technology controller:
– Enable: p2200 = 1
– Fixed value 1: p2201 = 26 %
– Ramp-up/down time for setpoint: p2257 = p2258 = 30 s
– Ramp-up/down time for controller output: p2293 = 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
• Default setting hibernation mode:
– Activated: p2398 = 1
– Start speed: p2390 = 50 rpm
– Delay time: p2391 = 60 s
– Restart value with technology controller: p2392 = 1 %
– Restart speed relative w/o technology controller: p2393 = 100 rpm
• "Flying restart" is enabled: p1200 = 1
• Automatic restart is active. After a power failure, the inverter automatically acknowledges possible
faults and switches on the motor: p1210 = 26
