Maximum speed / n_max

VECTOR_G Can be changed: C2(1), T

Min
0.000 [rpm]
Description: Sets the highest possible speed.
Dependency: For vector control (p1300 = 20 ... 23) the maximum speed is limited to 60.0 / (8.333 x p0115[0] x r0313). This can be
identified by a reduction in r1084. p1082 is not changed in this process due to the fact that the operating mode p1300
can be changed over.
If a sine-wave filter (p0230 = 3) is parameterized as output filter, then the maximum speed is limited corresponding to
the maximum permissible filter output frequency (refer to the filter data sheet). When using sine-wave filters (p0230 =
3, 4), the maximum speed r1084 is limited to 70% of the resonant frequency of the filter capacitance and the motor
leakage inductance.
For reactors and dU/dt filters, it is limited to 150 Hz * 60 / r0313 (for chassis power units) or 120 Hz x 60 / r0313 (for
booksize power units).
Refer to: p0115, p0230, r0313, p0322, p0324, r0336, p0532
Notice: After the value has been modified, no further parameter modifications can be made and the status is shown in r3996.
Modifications can be made again when r3996 = 0.
Note: The parameter applies for both motor directions.
The parameter has a limiting effect and is the reference quantity for all ramp-up and ramp-down times (e.g. down
ramps, ramp-function generator, motor potentiometer).
Since the parameter is part of quick commissioning (p0010 = 1), it is defined appropriately when p0310, p0311,
p0322, p0324, p0530, p0531, and p0532 are changed.
The following limits are always effective for p1082:
p1082 <= min(p0324, p0532) if p0324 > 0 and p0532 > 0
p1082 <= p0322 if p0324 = 0 or p0532 = 0 and p0322 > 0
p1082 <= 60 x minimum (15 x r0336, 650 Hz) / r0313
p1082 <= 60 x Maximum power unit pulse frequency / (k x r0313)
k = 12 for vector control (r0108.2 = 1), k = 6.5 for U/f control (r0108.2 = 0)
For the automatic calculation (p0340 = 1) the value of the parameter is pre-assigned the maximum motor speed
(p0322). If p0322 = 0, the rated motor speed (p0311) is used as default (pre-assignment) value. For induction motors
that are not catalog motors (p0301 = 0), the synchronous no-load speed is used as default (pre-assignment) value
(p0310 x 60 / r0313).
For synchronous motors, the following additionally applies:
The maximum speed p1082 is restricted to speeds (r1084) where the EMF does not exceed the DC link voltage.
The effective assignment of the motor data set parameter (e.g. p0311) to the drive data set parameter p1082 when
pre-assigning should be taken from p0186.
p1082 is also available in the quick commissioning (p0010 = 1); this means that when exiting via p3900 > 0, the value
is not changed.
