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 100

500 ms

Note: The Ramp-up, Ramp-down, and Minimum Speed parameters are shown for the tuning process of the actual stair-press system, and may

have to be adjusted to suit.

p1080[0] Minimum speed 450 rpm

p1120[0] Ramp-function generator ramp-up time 30 s

p1121[0] Ramp-function generator ramp-down time 30 s

p1210 Automatic restart, mode

[26] Acknowledging all faults and reclosing for an ON

command

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

p2201[0] CO: Technology controller, fixed value 1 40 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 120 Pa

p2268 Technology controller lower limit actual value -10 Pa

Note: The Prop gain and Integral time parameters are shown for the tuning process of the actual stair-press system, and may have to be adjusted

to suit.

p2280 Technology controller proportional gain 1.2

p2285 Technology controller integral time 25 s

Note: Set the PID Loop minimum output value to match the minimum motor speed (P1080). For example; 30% for 15Hz (when the max speed is

50Hz).

p2292 CO: Technology controller minimum limiting 30 %

p2302 Technology controller output signal starting value 35 %

p3880 BI: ESM activation Control_Unit : r722.0

p3881 ESM setp source [4] Setpoint from technology controller

p3884 CI: ESM setpoint technology controller Control_Unit : p2201

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