p0500 Technology application / Tec application
Access level: 2
Can be changed: C(1, 5), T
Unit group: -
Min
0
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: 0:
2:
Dependency: Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1), "Dynamic Drive Control" (DDC, p0096
= 2)
Notice: If the technological application is set to p0500 = 0, 2 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 = 0 and when the calculation is initiated, the following parameters are set:
- p1574 = 10 V
- p1750.2 = 0
- p1802 = 4 (SVM/FLB without overcontrol)
- 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
- p1802 = 4 (SVM/FLB without overcontrol)
- p1803 = 106 %
For p1750:
The setting of p1750 is only relevant for induction motors.
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.
For p1802 / p1803:
p1802 and p1803 are only changed, in all cases, if a sine-wave output filter (p0230 = 3, 4) has not been selected.
p0505 Selecting the system of units / Unit sys select
Access level: 1
Can be changed: C(5)
Unit group: -

Description: Sets the actual system of units.
Value: 1:
2:
3:
4:
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.
