Parameters
7.2 Parameter list
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).
The parameter is part of the quick commissioning (p0010 = 1); this means that it is appropriately pre-assigned when
changing p0310, p0311, p0322.
The following limits are always effective for p1082:
p1082 <= 60 x minimum (15 x p0310, 550 Hz) / r0313
p1082 <= 60 x maximum power unit pulse frequency / (k x r0313), with k = 12 (vector control), k = 6.5 (U/f control)
During automatic calculation (p0340 = 1, p3900 > 0), the parameter value is assigned the maximum motor speed
(p0322). For p0322 = 0 the rated motor speed (p0311) is used as default (pre-assignment) value. For induction motors,
the synchronous no-load speed is used as the default value (p0310 x 60 / r0313).
For synchronous motors, the following additionally applies:
During automatic calculation (p0340, p3900), p1082 is limited to speeds where the EMF does not exceed the DC link
voltage.
p1082 is also available in the quick commissioning (p0010 = 1); this means that when exiting via p3900 > 0, the value
is not changed.

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.
