0: 1000Hz
The measuring frequency is changed indepen-
dently during measurement.
Therefore, leave the value at 0: keep 1000Hz!
32: 500Hz
64: 250Hz
96: 125Hz
128: 62.5Hz
160: 32.25Hz

7.6.3.3.1 Auto-identication
The automatic identication can be carried out with rotation (dr.48=8) or without rotation (dr.48 = 7) (see table
dr.48). The measurement of the dead time compensation characteristics as well as stator resistance and lea-
kage inductance occurs during standstill.
For EMC identication it is necessary to accelerate the motor onto 60% of its rated speed. For this case an
additional ramp of dr.49 "Lh ident. acc/dec time" is effective". Calculation of the ramp can be taken from chapter
7.6.3.4.
