Parameter Parameter text Parameter Value Unit

Note: To change P0595 you first need to set P0010 = 5, and then set P0010 back to 0 afterwards.

p595 Selecting technological units [5] Pa

p596 Reference quantity, technological units 500

p753[0] CU analog inputs smoothing time constant, AI0 (T. 3/4) 500 ms

p756[0] CU analog inputs type, AI0 (T. 3/4) [0] Unipolar voltage input (0 V ... +10 V)

p1015[0] CO: Fixed speed setpoint 15 1350 rpm

p1080[0] Minimum speed 300 rpm

p1113[0] BI: Setpoint inversion 0

p1210 Automatic restart, mode

[26] Acknowledging all faults and reclosing for

an ON command

Note: When using ECO mode, set P1335 = 100% to enable slip compensation for correct operation.

p1300[0] Open-loop/closed-loop control operating mode

[7] U/f control for a parabolic characteristic and

ECO

p1335[0] Slip compensation, scaling 100 %

p2200[0] BI: Technology controller enable Control_Unit : r722.0

Note: Set pressure setpoint to suit application. This example assumes a 0-500Pa range sensor is used (e.g. QBM66.202 hi-range).

p2201[0] CO: Technology controller, fixed value 1 200 Pa

p2253[0] CI: Technology controller setpoint 1 Control_Unit : p2201

p2264[0] CI: Technology controller actual value Control_Unit : r755[0]

p2267 Technology controller upper limit actual value 600 Pa

p2268 Technology controller lower limit actual value -50 Pa

p2280 Technology controller proportional gain 1.1

p2285 Technology controller integral time 35 s

p2292 CO: Technology controller minimum limiting 20 %

p2302 Technology controller output signal starting value 50 %

p3880 BI: ESM activation Control_Unit : r722.1

p3881 ESM setp source [1] Fixed speed setpoint 15 (p1015)

Note: The following read-only parameters are shown as handy points of interest. Do not try to program these into your drive.

r755[0] CU analog inputs actual value in percent, AI0 (T. 3/4) 71.34 %

r2260 CO: Technology controller setpoint after ramp-function generator 200 Pa

r2272 CO: Technology controller actual value scaled 356.72 Pa

r2294 CO: Technology controller output signal 0 %
