Function parameter for selecting various start-up sections
and special functions.
Parameter values:
0 = No calculation
1 = Start of the calculation of derived motor data:
Additional motor data needed for vectorial current
control can be calculated from the entered rating plate
data.
As a result, these no longer have to be entered
separately. The following parameters are set
by the calculation:
P103 Motor no-load current
P120 Main field inductance
P121 Stator resistance
P122 Total leakage reactance
P123 Stator reactance
P124 Rotor time constant
P293 Field-weakening frequency
P294 Select flux reg
2= Selection of motor identification at standstill:
With the next ON command the automatic motor
identification and parameterization of closed-loop
control are performed from the measured motor data.
The following parameters are set by the identification:
P111 Ls = f(Isd)
P119 Ratio Lq/Ld
P120 Main field inductance
P121 Stator resistance
P122 Total leakage reactance
P123 Stator reactance
In the case of current-controlled operation (P290=0),
automatic motor identification should always be
performed on start-up.
In the case of P095=3 or 4, automatic parameterization
(P115=1) should be called after entry of all motor data
and before the start of automatic motor identification.
Warning:
The motor is live, and the rotor behaves accordingly.
The shaft may turn. After the P button has been
pressed, alarm "A078" appears. The converter must
be switched on within 20 s.
4=Selection of no-load measurement for induction motors
With the next ON command a no-load measurement
and parameterization of the closed-loop control are
performed from the measured data.
To carry out this measurement, the motor shaft
should not be connected to any mechanical loads.
The following parameters are set:
P103 No-load current
P111 Ls = f(Isd)
P121 Stator resistance
P122 Total leakage reactance
P123 Stator reactance
P124 Rotor time constant
Warning: The motor is live, and the rotor
behaves accordingly. After the P button
has been pressed, alarm "A078" appears.
The converter must be switched on within 30 s.
8=Position test for synchronous motors
In this status after power up, a stator current is
impressed with U(-), V and W(+), the absolute value
of which is entered via Isq (P270, P271).
If the motor is free to move slightly, a misorientation
