For p0500 = 3 and when the calculation is initiated, the following parameters are set:
- p1570 = 103 % (flux boost for full load)
- p1580 = 100 % (efficiency optimization)
- p1574 = 2 V
- p1750.2 = 1: Encoderless control of the induction motor is effective down to zero frequency.
- p1802 = 9 or 19 (optimized pulse pattern for p0300 = 14 )
- 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: Setting to inhibit the calculation of reference parameters (e.g. p2000) when automatically calculating the motor and
closed-loop control parameters (p0340, p3900).
Value: 0: No
1: Yes
Notice: The inhibit for the reference value calculation is canceled when new motor parameters (e.g. p0305) are entered and
only one drive data set exists (p0180 = 1). This is the case during initial commissioning.
Once the motor and control parameters have been calculated (p0340, p3900), the inhibit for the reference value
calculation is automatically re-activated.
Note: If value = 0:
The automatic calculation (p0340, p3900) overwrites the reference parameters.
If value = 1:
The automatic calculation (p0340, p3900) does not overwrite the reference parameters.
Description: Selects the units for the parameters of the technology controller.
For p0595 = 1, 2, the reference quantity set in p0596 is not active.
Value: 1: %
2: 1 referred no dimensions
3: bar
