Par. identification
(parameter identification)
0 ... 2
In devices with output of up to 22 KW the motor data is determined automatically by the device via
these parameters. In many cases, better drive behavior is achieved with the measured motor data.
{ 0 }
The identification of all parameters takes some time. Do not switch off the line voltage during this
time. If there is unfavorable operating behavior after identification, select a suitable motor in P200
or set parameters P201 ... P208 manually.
0 = no identification
1 = identification R
2 = motor identification:
Please note: Motor identification should only be carried out on a cold motor (15°C ... 25°C). Warming up of the
motor is taken into account during operation.
The VFD must be in the "ready for operation" state. For BUS operation, the BUS must operate
without error.
The motor output may only be one output level greater or 3 output levels lower than the rated
output of the VFD.
A maximum motor cable length of 20 m must be maintained for reliable identification.
Before starting motor identification, the motor data must be preset in accordance with the
nameplate or P200. The rated frequency (P201), the rated speed (P202), the voltage (P204), the
output (P205) and the motor circuit (P207) must at least be known.
Make sure that the connection to the motor is not interrupted during the entire measuring process.
If identification cannot be concluded successfully, error message E019 is generated.
After identification of parameters, P220 is again = 0.

EMF voltage PMSM
(PMSM EMF voltage)
0 ... 800 V
The EMF constant describes the mutual induction voltage of the motor. The value to be set can be
found on the data sheet for the motor or on the nameplate and is scaled to 1000 rpm. As the rated
{ 0 }
speed of the motor is not usually 1000 rpm, this must be converted accordingly:
Example:
E (EMF constant, nameplate):
Nn (rated speed of motor):

The stator resistance (display in P208) is determined by multiple measurements.
This function can only be used in devices of up to 22 KW.
ASM: all motor parameters (P202, P203, P206, P208, P209) are determined.
PMSM: stator resistance (P208) and inductance (P241) are determined.
