The motor data is automatically determined by the FI with this parameter. In most cases this
leads to considerably better drive characteristics, as DC asynchronous motors are subject to
manufacturing tolerances which are not documented on the rating plate.
If unfavorable operating characteristics result, select a suitable motor in P200 or set the
parameters P201 … P208 manually.
0 = No identification
1 = Identification RS: only the stator resistance (display in P208) is determined.
2 = Motor identification: all motor parameters (P202, P203, P206, P208, P209) are
determined.
Procedure: a) The identification should be made with the motor cold. Warming up of the motor during
operation is automatically taken into account.
b) The FI m ust be in an “operative condition”‘. For Bus operation, the Bus must be
operating without error. The FI must not be in a state of switch-on block.
c) The motor power may only be one power level greater or 3 power levels lower than the
nominal power of the FI.
d) The motor data should be set according to the rating plate or P200. However, at least
the nominal frequency (P201), the nominal speed (P202), the voltage (P204), the power
(P205) and the motor circuit (P207) should be known.
e) If the identification cannot be concluded successfully, the error message E019 is
generated. See also Section 6, Error messages.
f) Reliable identification can be made with motor cables up 20m in length.
NOTE:
After identification of parameters, P220 is again = 0.
Care must be taken that the connection to the motor is not interrupted during the
entire measuring process.
