0000 1100 bi Configuration of the OBT. The following settings are possible:
n
● Bit 03: Activates speed precontrol
– Only relevant for EPOS.
● Bit 04: Activates torque precontrol
– If EPOS is active, then the torque precontrol from EPOS is used
(p2567).
– If EPOS is not active, then the speed/torque precontrol of the
speed controller is used (p1493, p1428, p1429).
● Bit 07: Activates voltage precontrol
‑ Display of the estimated position controller gain for OBT:
● If position control is implemented using a higher-level open-loop
control system, the open-loop control system can assume the
values displayed here.
‑ Display of the estimated precontrol symmetrizing time of the position
controller for OBT:
● If position control is implemented using a higher-level open-loop
control system, the open-loop control system can assume the
values displayed here.
80% Dynamic response factor for the P gain of the speed controller:
● The speed control may become instable if the values are too high.
‑ Display of the proportional gain established for the speed controller,
calculated from the FFT measurement by OBT
‑ Display of the identified mechanical zero positions
‑ Display of the identified mechanical pole positions
10% Setting the amplitude of the noise signal for the functions p5301.0 and
p5301.1.
● The value refers to the rated torque of the motor r0333.
30% Setting the amplitude of the noise signal for the functions p5301.4 and
p5301.5:
● The value refers to the rated torque of the motor r0333.
0 rpm Setting the rotational feed offset for the functions p5301.0 and p5301.1:
● The setting should prevent non-linear effects, such as backlash or
stiction, influencing the measured values.
0 m/min
0 rpm Setting the rotational feed offset for the functions p5301.4 and p5301.5:
● The setting should prevent non-linear effects, such as backlash or
stiction, influencing the measured values.
0 m/min
‑ Status display of the auto tuning functions that have been executed:
● The display relates to the action of the p5300 last executed, and is
therefore not only applicable for the OBT.
