Description: Sets the hysteresis for the changeover speed/velocity of the motor model.
Dependency: Refer to: p1752, p1755
Note: The value is entered relative to p1404, p1752 or p1755.

Description: Induction motor (ASM):
Displays the difference between the motor model flux angle and the transformation angle.
Permanent-magnet synchronous motor (PESM):
Displays the angular difference between motor model and encoder.
Dependency: A setting for smoothing the display can be made using p1754.
Notice: The display only makes sense for corrected actual value inversion, encoder pulse number and pole pair number.
Example:
Moving in encoderless operation at a speed not equal to zero and without load.
--> Check the sign of r0061 and r0063. If the sign is not equal, then change p0410.0.
--> Check the stationary value of r0061 and r0063. If the value is not equal, change the encoder pulse number
(p0408) or pole pair number (p0314).

Not for motor type: -

1.000 [kHz]
Description: Sets the pulse frequency for the converter.
This parameter is pre-set to the rated converter value when the drive is first commissioned.
Dependency: The pulse frequency can, depending on the current controller sampling time (p0115[0]) assume the following val-
ues:
a) p1800 = 1000 / (p0115[0] * n) mit n = 2, 3, 4, 5
b) p1800 = 1000 * n / p0115[0] with n = 1, 2, 3, 4, ...
Example:
p0115[0] = 125 µs -> p1800 = 1.6, 2, 2.6, 4 kHz (from equation a)
p0115[0] = 125 µs -> p1800 = 8, 16 kHz (from equation b)
Possible setting values can be taken from r0114 (if p0009 = p0010 = 0).
Note: The maximum possible pulse frequency is also determined by the power unit being used.
When the pulse frequency is increased, depending on the particular power unit, the maximum output current can be
reduced (derating, refer to r0067).
