Start-up
9. Calculation of motor-dependent data
Even if the motor data dr.06 to dr.10 are unknown, the motor-
dependent data (e.g. dr.18 field weak. speed) must be cal-
culated here.
⇒ Fr.10 load motor-dep. parameter = 2: act. DC link voltage
10. Identification of the equivalent circuit data
The equivalent circuit data dr.06...dr.10 can be automatically
determined by the KEB COMBIVERT.
The following must be considered:
• The motor must be in no-load operation for identification
of the main inductance. As standard the motor rotates with
dr.17: „speed for max torque". The speed limits (oP-Parame-
ter/chapter 7.4.5) must be programmed accordingly if this is
not permissible.
• The direction of rotation is clockwise, the acceleration time
is preset by dr.49: „Lh.ident. acc/dec time"
• The speeed controller must be parameterized for acce-
leration (dynamics not necessary => select small value for
cS.09: KI speed)
• The brake control mode must be activated
(corresponding to KEB factory setting)
• After successful measurement ru.00 = 127 (drive data cal-
culated/Cddr) is displayed.
The identification is started with:
⇒ dr.48 = 8: complete AutoIdentification !with rotation!
Close control release (X2A.16) for starting the identification
and open it after the measurement.
Adjustment of specific data

⇒ dS.02 current decoupling = 1: on
⇒ uF.15 hardw. curr. lim. mode = 0: off
⇒ uF.18 deadtime comp. mode = 3: automatically

Attention:
Depending on the used motor the iden-
tification takes some minutes. Noises
in the motor can occur caused by high
frequency test signals. The sequence of
the identification can be tracked in para-
meter dr.62 „state motor ident.".
Since the drive is not optimally parame-
terized, a flat acceleration ramp (dr.49)
should be selected for the identification
to avoid overload of the motor
Note:
If the measurement is interrupted with
an error, ru.00 = 60 (error! drive data /
E.Cdd) is displayed.
Read chapter 7.6 for further data of the
identification.
