List Manual, 09/2017, A5E33842890
Dependency:
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 or 5
Not visible with application class: "Standard Drive Control" (SDC, p0096 = 1)
Refer to: p1610, p1750
Note:
When entering p0502 and initiating the calculation, the following parameters are set:
p0502 = 0:
- p1750.0/1/7 = 1 (start and reverse in open-loop control with rugged switchover limits)
- p1610 = 50 %, p1611 = 30 % (low up to average starting torque)
p0502 = 1:
- p1750.0/1/7 = 0 (start and reverse in closed-loop speed control with shorter acceleration times)
- p1610 = 50 %, p1611 = 30 % (only effective, if the drive is switched-on with a speed setpoint of zero)
p0502 = 5:
- p1750.0/1/7 = 1 (start and reverse in open-loop control with rugged switchover limits)
- p1610 = 80 %, p1611 = 80 % (average up to higher starting torque)
p1750.6 = 1 is always set, p1574 (voltage reserve) is preassigned, depending on p0205 (power unit application).
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 p1744, p1752, p1755).
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 values for the specific scaling of BICO parameters.
The specific scaling is active when interconnecting with other BICO parameters, and can be used in the following
cases:
1. Parameter with the marking "Scaling: p0514".
2. Changing the standard scaling for parameters with the marking "Scaling: p2000" ... "Scaling: p2007".
Relative values refer to the corresponding reference value. The reference value corresponds to 100% or 4000 hex
(word) or 4000 0000 hex (double word).
To specifically scale BICO parameters, proceed as follows:
- set the reference value (p0514[0...9]).
- set the numbers of the parameters, which should be active for the scaling, corresponding to the index of p0514
(p0515[0...19] ... p0524[0...19]).
For parameters with the marking "Scaling: p0514", which are not entered in p0515[0...19] to p0524[0...19], the
reference value 1.0 (factory setting) applies.
