2.2 List of parameters
For p0500 = 1 and when the calculation is initiated, the following parameters are set:
p1574 = 2 V (separately-excited synchronous motor: 4 V)
p1750.2 = 0
p1802 = 9 (edge modulation), if r0192.0 = 1
p1802 = 4, if r0192.0 = 0
p1803 = 106 %
For p0500 = 2 and when the calculation is initiated, the following parameters are set:
p1574 = 2 V (separately-excited synchronous motor: 4 V)
p1750.2 = 1: Encoderless control of the induction motor is effective down to zero frequency.
This operating mode is possible for passive loads. These include applications where the load does not generate
regenerative torque when breaking away and the motor comes to a standstill (zero speed) itself when the pulses are
inhibited.
p1802 = 4 (SVM/FLB without overcontrol)
p1803 = 106 %
The setting of p1750 is only relevant for induction motors.
p1802 and p1803 are only changed, in all cases, if a sine-wave output filter (p0230 = 3, 4) has not been selected.
For p0500 = 4: (presetting for VECTOR with PM250 power unit)
p1574 = 30 V
p1750.2 = 0
p1802 = 2 (SVM with overcontrol)
p1803 = 106 %
Description: Sets the actual system of units.
Value: 1: SI system of units
2: System of units referred/SI
3: US system of units
4: System of units referred/US
Dependency: The parameter can only be changed in an offline project using the commissioning software.
Caution: If a per unit representation is selected and if the reference parameters (e.g. p2000) are subsequently changed, then
the physical significance of several control parameters is also adapted at the same time. As a consequence, the
control behavior can change (see p1576, p1621, p1744, p1752, p1755 and p1609, p1612, p1619, p1620).
Note: Reference parameter for the unit system % are, for example, p2000 ... p2004. Depending on what has been
selected, these are displayed using either SI or US units.
Description: Sets the reference quantities for the user-specific scaling.
By indexing reference parameter p514[0..9], a total of 10 reference quantities are available:
p514[0]reference quantity 01
p514[1]reference quantity 02
..
p514[8]reference quantity 09
