Adapt. dynamics
[469]
Dynamics of the motor mathematical model adaptation controller.
40
Hz
1 Hz ÷ 300 Hz
Coef. avoid 0Hz
[1184] Zero speed avoiding coefficient, it is used for flux change for rapid change of stator
frequency. Value 1 means no flux change.

POSITIONING
Group of parameters number [832]
Parameters for simple single-axis position control applications. Position control can be turned on by the
parameter Control type [835] (page 57). For setting the position control, it is necessary to set up source of
position setpoint Pos. source [1136] (page 53), feedback Pos. feedback source [1141] (page 66), position
limits Min. position setpoint [1139] (page 53) and Max. position setpoint [1140] (page 53) and position
calibration Pos. calib. source [1144] (page 66).

0,0000 ÷ 5,0000
Dead-zone stat. [1548] Position dead-zone at zero speed at gear output in revolutions. 0,00000000
Min. position setpoint
[1139] ÷ Max. position
setpoint [1140]
Pos. feedback source
[1141] Selecting the source of the position feedback ( Position [1147]
(page 17)).
IRC1
IRC1 Position feedback is evaluated from IRC1.
IRC2 Position feedback is evaluated from IRC2.
IRC1-IRC2 Position feedback is evaluated as the difference of IRC1 and IRC2.
ARC Position feedback is evaluated from the absolute position sensor.
ARC-IRC1 Position feedback is evaluated as the difference of ARC and IRC1.
ARC-ARCmaster Position feedback is evaluated as the difference of ARC and ARCmaster.
Special
Special feedback source, feedback value is taken from Special position [1142]
(page 66).
Special position [1142] Value of special position source. 0,000
Min. position setpoint
[1139] ÷ Max. position
setpoint [1140]
Position overflow [1143]
Number of revolutions (absolute value) after which the position
overflows and position is recalibrated. By setting it to zero, the
position never overflows.

Pos. calib. source [1144]
Source of the position calibration. The position will be set to the
value Calibration pos. [834] (page 66).

Calibration pos. [834]
Value, which will be stored as position value on the rising edge of
the calibration signal Pos. calib. source [1144] (page 66).
