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.
