Note: Re bit 07:
The interpolator is only effective for clock-cycle synchronous PROFIBUS operation and when the master receives a
sign-of-life (STW 2.12 ... STW 2.15). Further, for active Dynamic Servo Control (DSC) an additional dead time of
one speed controller clock cycle is obtained.
Re bit 10:
The pre-control signal via connector input p1430 only becomes effective at p1402.4 = 1 (torque-speed pre-control
with encoder) at p1400.10 = 0 (for setp_filter 2).
Re bit 11:
If the motor rotates when the pulses are enabled, then we recommend p1400.11 = 1 (starting value = setpoint) with
the matching sign.
If the motor remains stationary (zero speed) when the pulses are enabled, the we recommend p1400.11 = 0 (start-
ing value = 0.0).
Re bit 12:
If a changeover is made from operation with encoder to encoderless operation while accelerating (with the thresh-
old from p1404), then we recommend p1400.12 = 0.
If the changeover is made from operation with encoder to encoderless at constant speed/velocity (e.g. with a DDS
changeover or if there is an encoder fault via p0491) then we recommend p1400.12 = 1.
Re bit 18:
Only active when the "moment of inertia estimator" function module is active (r0108.10 = 1).
For operation with encoder, in addition, p1402.4 must be set to 1.
The result of the moment of inertia estimator is displayed in r1493 when the function is activated.
The function assumes that speed changes are made without load. If a speed change must be realized under load,
then during this time, the estimated moment of inertia should be frozen using binector input p1502.

01 Park encoder for n_act > p1404
02 Current controller adaptation active
04 Torque-speed pre-control with encoder
Note: Re bit 01:
When the bit is set, the encoder is parked as soon as the actual speed is greater than the changeover speed
(p1404). The encoder state is indicated in r0481.14.
