The identification is only executed for the parameter set which is activated
at the moment:
ƒ If you want to identify the motor dat for another parameter set, you
must switch to this parameter set and restart the identification.
Note!
ƒ During the identification the motor is supplied with current.
The motor does not rotate.
ƒ The load machine can remain t o be connected. Existing
holding brakes can be kept in the braking position.
ƒ If the motor is idling, a small phase offset may occur at the
motor shaft.
1. Enter C0087, C0088, C0089, C0090 and C0091 of your motor (see
nameplate):
– It is vital to enter the correct values since these entries influence
important parameters such as slip compensation and no-load
current.
– Enter the values according t o the connection method (star or delta)
for the rated motor current (C0088) and rated motor voltage (C0090).
1. Inhibit the controller. Wait until drive stands still.
2. Select C0148 = 1, confirm with .
3. Enable the controller. The identification starts.
– The green LED at the controller is blinking very fast.
– ”WRK run” is displayed at the keypad.
– The rotor resistance is c alculated and saved in C0082.
– The motor stator resistance is detected and saved in C0084.
– The motor l eakage inductance is measured and saved in C0085.
– The inverter compensation characteristic is calculated from the
measured motor stator resistance and saved in C1751/1 ... C1751/17.
– The motor stator inductance is calculated from the entered data and
saved in C0092.
– The identification takes approx. 1 ... 2 min (dependent on the rated
motor power).
– The identification is completed when the green LED at the controller
is lit (keypad, GDC: is active).
4. Inhibit the controller.
If the motor data identification is has been completed incorrectly
If the identification is incorrect, the fault ID1 or ID2 is displayed.
ƒ If the motor data identification is incorrect, the process must be
repeated from step 2.
