The identification is only executed for the parameter set which is activated
at the moment:
ƒ If you want to identify the motor data 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 to 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 to 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
v.
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 calculated and saved in C0082.
– The motor stator resistance is detected and saved in C0084.
– The motor leakage 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:
c is active).
4. Inhibit the controller.
If the motor data identification 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.
