p0505 Selecting the system of units / Unit sys select
Access level: 1
Can be changed: C(5)
Units group: -
Min
1
Description: Adjustable parameter of the actual system of units.
Value: 1:
2:
3:
4:
Dependency: The parameter cannot be changed if the master control was fetched.
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.
p0573 Inhibit automatic reference value calculation / Inhibit calc
Access level: 3
Can be changed: U, T
Units group: -
Min
0
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:
1:
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.
