SINAMICS G120 CU230P-2 Control Units List Manual (LH9), 01/2013
Description: Sets the technology application.
The parameter influences the calculation of open-loop and closed-loop control parameters that is e.g. initiated using
p0340 = 5.
Value: 1: Pumps and fans
3: Pumps and fans, efficiency optimization
Notice: If the technological application is set to p0500 = 0 ... 3 during commissioning (p0010 = 1, 5, 30), the operating mode
(p1300) is pre-set accordingly.
Note: The calculation of parameters dependent on the technology application can be called up as follows:
- when exiting quick commissioning using p3900 > 0
- when writing p0340 = 1, 3, 5
For p0500 = 1 and when the calculation is initiated, the following parameters are set:
- p1570 = 100 %
- p1580 = 0 % (no efficiency optimization)
- p1574 = 2 V
- p1750.2 = 0
- p1802 = 9 or 19 (optimized pulse pattern for p0300 = 14 )
- p1803 = 106 %
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 cannot be changed when master control is active.
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.
