Automatic identification
The automatic identification of the Lh-characteristic is started via bit 10 of the parameter
Z146.1– (mode asynchronous machine). At the same time the status Current presetting
of the drive is checked. Nominal speed, speed for Lh identification, nominal magnetizing
current and ramp-up time must be preset. Then it is accelerated to the desired speed
(
Z123.39–) with nominal magnetizing current. Thereby a linear ramp calculated from the
ramp-up time is used. Then the motor successively is supplied with a step size of 1/20 of
the nominal magnetizing current at this speed. Thereby the required voltage is measured.
As it is estimated that the drive is in idle state, the inductance can be calculated with the
acceptability that the slip = 0.
It is decelerated and the inductances are standardized to nominal inductance and entered
in the table.
