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 auto identification! with rotation!
Close control release (X2A.16) for starting the identification
and open it after the measurement.
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
parameter dr.62 „state motor ident.".
Since the drive is not optimally para-
meterized, a flat acceleration ramp
(dr.49) should be selected for the iden-
tification 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.
