In U953.41 ... 45 only the values
0 or 20 can be entered.
Note:
If interconnection is effected against the
sequence, there is a dead time of T0 in
the speed control loop
(e. g. KK0152 -> P252, KK1058 -> P228)

Reference speed P353 must be chosen so
that the total of setpoints P224 and P225 is
always < 195 %.
