) Note!
Ensure that the motor is cold when the identification is
started!
l During identification current flow via the controller outputs U, V.
l The load machine can remain connected. Holding brakes can
remain in their braking position.
l With idling motors a small angle shift can occur at the motor
shaft.
1. Inhibit the controller. And wait until the drive is in standstill.
2. Enter C0087, C0088, C0089, C0090 and C0091 of your motor (see
nameplate):
– It is absolutely necessary to enter correct data since important
parameters such as slip compensation, idle running current and I
2
t
monitoring are based on these values.
– Enter rated motor current (C0088) and rated motor voltage (C0090)
according to the connection type (star or delta).
3. Select C0148 = 1, confirm with v.
4. Enable controller. Identification starts (green controller LED blinking quickly).
– The motor stator resistance is measured and stored under C0084.
– The motor stator inductance is calculated from the data entered and
stored under C0092.
– The V/f rated frequency is calculated and stored under C0015.
– The slip is calculated and stored under C0021.
– The identification takes approx. 30 s.
– Identification is completed when the green controller LED comes on
(keypad, GDC: c is active).
5. Inhibit the controller.

) Note!
Only the parameter set activated via the digital input signals will
be identified.
If you want to detect motor data for any other parameter set,
this parameter set must be activated via digital input signals
before it can be identified.
l The motor data are corrected automatically during operation (max. ±25 %)
to compensate for temperature fluctuations.
– The values under C0084 and C0092 calculated by C0148 become active
after mains switching.
l The values under C0084 and C0092 can be manually entered or corrected.
