Re bit 20 (speed calculation mode):
- if bit = 1, the speed is calculated via incremental difference without extrapolation.
- if bit = 0, the speed is calculated via edge time measurement with extrapolation. p0453 is effective in this mode.
Re bit 21 (zero mark tolerance):
- if bit = 1, a one-off zero mark distance error is tolerated. In the event of a defect, the fault F3x100/F3x101 does not
appear, but alarm A3x400/A3x401 does.
Re bit 22 (rotor position adaptation):
- if bit = 1, the rotor position is corrected automatically. The correction speed is +/-1/4 encoder pulse per zero mark
distance.
Re bit 23 (de-select commutation with zero mark):
- The bit should only be set for encoders that have not been adjusted.
Re bit 24 (commutation with selected zero mark):
- if bit = 1, the commutation position is corrected via a selected zero mark.
Re bit 25 (disconnect the encoder power supply on parking):
- if bit = 1, the encoder power supply is switched off on parking (0 V).
- if bit = 0, the encoder power supply is not switched off on parking, it is reduced from 24 V to 5 V.
Re bit 27 (extrapolate position values):
- if bit = 1, the extrapolation of the position values is activated.
Re bit 28 (cubic correction);
- if bit = 1, the cubic correction for track A/B sine is activated.
Re bit 29 (phase correction):
- if bit = 1, the phase correction for track A/B sine is activated.
Re bit 30 (amplitude correction):
- if bit = 1, the amplitude correction for track A/B sine is activated.
Re bit 31 (offset correction):
- if bit = 1, the offset correction for track A/B sine is activated.
Description: Sets the angular commutation offset.
Dependency: The value is taken into account in r0094.
Refer to: r0094, r1778
Caution: When the firmware is upgraded from V2.3 to V2.4 or higher, the value must be reduced by 60° if all the following
conditions are fulfilled:
- The motor is a synchronous motor (p0300 = 2, 2xx, 4, 4xx).
- The encoder is a resolver (p0404.23 = 1).
- The actual speed value is inverted (p0410.0 = 1).
Notice: The angular commutation offset cannot be generally taken from other drive systems. As a minimum - the sign of the
offset determined for SIMODRIVE 611 digital and SIMODRIVE 611 universal must be reversed for SINAMICS
(p0431 (SINAMICS) = -p1016 (SIMODRIVE)).
Note: Angular commutation offset, angular difference between electrical position of encoder and flux position.
For p0404.5 = 1 (track C/D) the following applies:
The angular offset in p0431 acts on track A/B, the zero mark on track C/D.
For p0404.6 = 1 (Hall sensor) the following applies:
The angular offset in p0431 acts on track A/B and the zero mark.
