For devices with powers up to 7.5 kW, the motor data is automatically determined by the FI via this
parameter. In many cases, a better drive behaviour is possible with the measured motor data.
The identification of all parameters takes some time. Do not switch off the mains voltage during
this time. If unfavourable operating characteristics result after identification, select a suitable motor
in P200 or set the parameters P201 … P208 manually.
0 = No identification
1 = R
S
identification: only the stator resistance (display in P208) is determined by multiple
measurements.
2 = Motor identification :all motor parameters (P202, P203, P206, P208, P209) are
determined. This function can only be used with devices up to 7.5 kW (230 V to 4.0 kW).
Note! Only carry out the identification of motor data when the motor is cold (15 … 25°C) Warming up of
the motor during operation is taken into account.
The FI must be in a “Standby” status For BUS operation, the BUS must be operating without error.
The motor power may only be one power level greater or 3 power levels lower than the nominal
power of the FI.
In order to enable reliable identification, the motor cable length must not exceed 20m.
Before starting the motor identification, the motor data according to the type plate or P200 must be
pre-set. At least the nominal frequency (P201), the nominal speed (P202), the voltage (P204), the
power (P205) and the motor circuit (P207) should be known.
Care must be taken that the connection to the motor is not interrupted during the entire measuring
process.
If the identification cannot be concluded successfully, the error message E019 is generated.
After identification of parameters, P220 is again = 0.

This parameter activates speed control with speed measurement via an incremental encoder.
This results in a very stable speed behaviour down to the standstill of the motor.
0 = Off
1 = No
NOTE:
For correct function, an incremental encoder must be connected and the correct pulse number
must be entered in parameter P301.
