Description: Setting to change the direction of rotation.
If the parameter is changed, it reverses the direction of rotation of the motor and the encoder actual value without
changing the setpoint.
Value: 0:
1:
Dependency: Refer to: F07434
Notice: An appropriate fault is output for a drive data set changeover where the direction of rotation changes and the pulses
are enabled.
Note: For operation with the phase sequence U/V/W, the direction of rotation is defined when viewing the face side of the
motor output shaft.
When changing the direction of rotation, the rotating field direction of the current controller is reversed. The speed
actual value (e.g. r0063) is also reversed so that the control sense is kept and internally causing the direction of
rotation to be reversed with the same setpoint. Further, the position actual values of the actual encoder are
reversed (e.g. r0482[0...2]).

-
Description: Sets the configuration for the motor data identification.
Recommend.: For the stationary motor data identification, if a motor holding brake is being used it should be opened and the
motor finely synchronized before the measurement. This should only be done if it can be safely carried out and no
external forces can act on the motor. This determines the angular commutation offset (p1909.13, p0431).

14 Determining the voltage emulation error
Dependency: Refer to: p1910, r1912, r1913, r1915, r1925, r1927, r1932, r1933, r1934, r1935, r1936, r1950, r1951
Note: For an induction motor (ASM) the following bits: 8, 9, 10, 13 are effective
For a synchronous motor (SRM) the following bits: 8, 9, 13, 14 are effective
Re bit 14:
- after successfully determining the voltage emulation error, the display of the phase voltage actual values r0089
and the active power actual value r0082 and the torque actual value r0080 are significantly more accurate.
- the voltage emulation errors should be identified with the Motor Module in the warm state.
- the motor temperature (r0035) should not change significantly (i.e. it should not be identified immediately after a
load duty cycle).
