Dependency: Refer to: p1958, p1960
Notice: The step p1959.8 (identify q inductance on the test stand) may only be selected if the drive can be kept at zero
speed or at a fixed speed either using a test stand or other mechanical measures.
During steps p1959.2 (identifying the moment of inertia) and p1959.6 (identifying the torque constant) the Vdc_min
controller is disabled (p1240).
During step p1959.7 (identifying the reluctance torque constant) the Vdc_min controller and Vdc_max controller are
disabled (p1240).
Note: For an induction motor (ASM), the following bits are effective: 1, 2, 5, 8, 9, 10, 14, 15
For a synchronous motor (SRM), the following bits are effective: 2, 5, 6, 7, 8, 10, 14, 15
Re bit 05:
For "motor holding brake the same as sequence control" (p1215 = 1 or 3), the Lq characteristic is only measured up
to approximately the rated motor current (p0305) instead of up to the current limit (p0640). Before carrying out the
rotation measurement for motors with brake, the brake should be opened (p1215 = 2) - as long as this can be done
without incurring any danger.
Re bit 10:
If the motor holding brake is set just the same as the sequence control (p1215 = 1 or 3), the commutation angle and
the direction of rotation are not measured. Before carrying out the rotation measurement for motors with brake, the
brake should be opened (p1215 = 2) - as long as this can be done without incurring any danger.
Re bit 14 and 15:
The following applies for bit 14 and 15 = 0:
When the function module "extended setpoint channel" is activated (r0108.8 = 1), the direction inhibit of the setpoint
channel becomes effective. No direction of inhibit is effective if the function module is inactive.
The following applies for minimum bit 14 = 1 or bit 15 = 1:
The direction inhibit set in p1959 becomes effective.
Description: Sets the configuration of the rotating measurement.
Recommend.: A direction inhibit should not be activated for the rotating measurement (p1959.14 = 1 and p1959.15 = 1) as long as
this can be done without incurring any danger. This means that the identification is complete and more accurate.
When the direction inhibit is activated, the reluctance force constant (p1959.7) is not identified and the angular com-
mutation offset (p1959.10, p0431) is inaccurately determined. The reluctance force constant (p1959.7) is also not
identified in sensorless operation.
