10.8 Automatic detection of motor data
Description
This function serves to determine the required motor data and influences of the motor
cable.
Must be carried out prior to initial commissioning of the vector control (C0014 = 4) or the
sensorless torque control (C0014 = 5). Otherwise commissioning will not be possible.
)
Note!
The motor data identification also influences the smooth running
performance in the "V/f characteristic control with constant V
min
boost"
operating mode (C0014 = 2 or 3). If motor data identification is carried out in
this operating mode, the smooth running performance can be optimised for
lower speeds.

Identifying
motor data 0 0 Ready Only when the motor is cold!
1. Inhibit controller, wait until
drive is at standstill
2. Enter the correct values from
the motor nameplate in C0087,
C0088, C0089, C0090, C0091
3. Set C0148 = 1, confirm with
v
4. Enable controller:
The identification
– starts,
c goes out
– the motor "whistles" faintly
but it does not rotate!
– takes approx. 30 s
– is completed when
c is lit
again
5. Inhibit controller

compensation (C0021) and motor
stator inductance (C0092) are
calculated and saved

and motor is measured and saved
