Additional settings:
• Pressure control using the technology controller
• Analog inputs smoothing time constant: p0753 = 500 ms
• Technological unit: p0595 = 1 (%), reference variable: p0596 = 1
• Fixed speed setpoint 15 for essential service mode (ESM): p1015 = 1350 rpm
• Default setting of the technology controller:
– Enable: p2200 = 1
– Fixed value 1: p2201 = 40 %
– 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

• "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
