WARNING
The motor data identification routine (refer to Section 3.5.4) may not be used for
loads which are potentially hazardous (e.g. suspended loads for crane
applications). Before the motor data identification run is started, the potentially
hazardous load must be carefully secured (e.g. by lowering the load to the floor or
by clamping the load using the motor holding brake).
NOTE
 The precise equivalent circuit diagram data are extremely important for the
voltage boost of the V/f characteristic. The equivalent diagram data can only be
estimated from the rating plate data. This is the reason that the equivalent
circuit diagram data are, either
- determined using the motor data identification routine (refer to Section 3.5.4),
or
- entered from the motor data sheet (refer to Section 3.5.3).
 Parameter P0308 or P0309 are only visible using the BOP or AOP if P0003 ≥ 2.
Depending on the setting of parameter P0100, either P0308 or P0309 is
displayed.
 The input value of P0307 and all other power data are either interpreted as kW
or hp value depending on P0100.
The possible rating plate / power plate data is shown in Fig. 3-17. The precise
definition and explanation of this data is defined in DIN EN 60 034-1.

In order to ensure a straightforward, successful commissioning, it is important that
the circuit connection in the motor terminal box (refer to Fig. 3-18) matches the
rated motor voltage entered in P0304 or the rated motor current P0305.
