The start value p2302 is only used in mode p2251 = 0. After enable of technology controller the start value is present as long as the RFG output reaches this value.
<3>
I component stop, only when r2273 and r2294 in same direction.
<4>
Recommendation for p2251 = 1: c2299 connected to r1150.
<5> Signal = 0 --> factor = 0, when setpoint from external operating tool or operator panel.
r2349.12 = 1, if p2345 > 0 and actual value limited and start value p2302 not active.
<2>
p2251 = 0: I component is stopped, when r2294 is below the minimum speed or within a suppression bandwidth.
