<3> Only for encoder:
p1400.10 = 1 is recommended if a torque pre-control signal is also
connected at [5060] in addition to the speed pre-control signal.
<4> The interpolator is only effective for clock-cycle synchronous
PROFIdrive operation and sign-of-life received from the master
(STW2.12 ... STW2.15).
<5> For a 1/0 edge from control command STW2.8 "travel to fixed
stop" [2444] the output of all filters is set to the input value for an
instantaneous response to a change of the speed setpoint sign.
<6> The value is displayed correctly only with r0899.2 = 1 (Operation
enabled).
