Configuring One Button Tuning The following settings are possible:
• 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
r5276 - - Displays the estimated position controller gain for One Button Tuning
If position control is implemented using a higher-level open-loop con-
trol system, the open-loop control system can assume the values
displayed here.
r5277 - - Displays the estimated precontrol symmetrizing time of the position
controller for One Button Tuning
If position control is implemented using a higher-level open-loop con-
trol system, the open-loop control system can assume the values
displayed here.
p5292 25 %...125% 80% Dynamic response factor for the P gain of the speed controller.
The speed control may become instable if the values are too high.
r5293 - - Display of the determined proportional gain of the speed controller
calculated from the FFT measurement through "One button tuning".
r5294 - - Display of the identified mechanical zero positions.
r5295 - - Display of the identified mechanical pole positions.
p5296[0] 1%...300% 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.
p5296[1] 1%...300% 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.

Setting the rotational feed offset for the functions p5301.0 and
p5301.1.
This should prevent non-linear effects, such as backlash or stiction,
influencing the measured values.

Setting the rotational feed offset for the functions p5301.4 and
p5301.5.
This should prevent non-linear effects, such as backlash or stiction,
influencing the measured values.
r5306[0...n] - - Status display of the auto tuning functions that have been executed.
The display refers to the last action of the p5300 (is therefore not
applicable for Button Tuning).
