Index: [0] = Run 1
[1] = Run 2
Dependency: Refer to: p3410
Note: The value measured in the first identification run (for p3410 = 1, 3, 4, 5) is displayed in r3412[0]. For p3410 = 1, 3,
this value is transferred to p3422.
The DC link capacitance is not measured at the second identification run.
The total DC link capacitance of a DC link group comprises the sum of the sub-capacitances of all motor/infeed
modules and the additional DC link capacitors.
Description: Displays the identified line supply inductance.
The value corresponds to the total inductance between the stiff line supply and the connection point of the Voltage
Sensing Module (VSM).
Index: [0] = Run 1
[1] = Run 2
Dependency: Refer to: p3410
Notice: The value is only automatically determined for the line supply identification (p3410 > 0), if operation with a Voltage
Sensing Module is selected (p3400.5 = 1). Otherwise, r3414 = 0 is displayed.
Note: The value measured in the first identification run is displayed in r3414[0] (for p3410 = 1, 3, 4, 5). This value is trans-
ferred to p3421.
The value measured in the second identification run is displayed in r3414[1] (for p3410 = 4, 5).
For the inductance value of the commutating reactor, r3411 - r3414 applies.
Description: Sets the magnitude of the excitation frequency for the L identification.
The setting is made as a percentage of the maximum power unit current (r0209).
Index: [0] = Run 1
[1] = Run 2
Dependency: Refer to: p3410, r3411, p3421, p3620, p3622
Notice: To correctly identify the current level (p3410 = 4, 5) depending on the reactor inductance, the following must apply:
p3415[0] < p3415[1]
For A_INF booksize units, the following applies:
The interrelationship between the reactor inductance and the current magnitude should be measured. Generally,
the factory setting of p3415[0] and p3415[1] should be kept.
For chassis units and S_INF booksize units, the following applies:
Generally, there is only a very low inter-relationship between the reactor inductance and the current magnitude.
This means that for the factory setting p3415[0] = p3415[1] = 20 %, i.e. run 2 is not executed.
Note: The reactive current for identification run 1 is set in p3415[0] (basic controller setting).
The reactive current for identification run 2 is set in p3415[1] (adaptation of the current controller when reducing the
reactor inductance with increasing current magnitude).
