Display of function parameters, monitoring parameters, and connectors
are limited to double the reference value.
After fast parameterization, the reference and rated motor values are
identical. This enables signal representation (e.g. via connectors) up to
twice the rated motor values. If this is not sufficient, you can switch to
the menu "Drive setting" (P060 = 5) to adapt the reference values. The
following parameters are available for that purpose:
P350 Reference current in A
P351 Reference voltage in V
P352 Reference frequency in Hz
P353 Reference speed in rpm
P354 Reference torque in Nm
Speed reference frequency and reference speed are always coupled
via the number of pole pairs.

If one of the two parameters is altered, the second is converted using
this equation.
The reference power (in W) is calculated from the reference torque and

For exact determination of the motor parameters, it is possible to carry
out automatic motor identification and speed controller optimization.
For this purpose, the procedures of the "Drive setting" have to be
observed. If one of the vector control types (P100 = 3, 4, 5) of a
converter without a sinusoidal output filter and of an induction motor
without an encoder or with a pulse encoder (correct number of pulses in
P151) is used, the motor identification procedure can be shortened. In
this case, "Complete motor identification" has to be selected (P115 = 3)
and the converter has to be powered up accordingly if the alarms A078
and A080 appear.
During motor identification inverter pulses are released and the drive
rotates!
For reasons of safety, identification should first be carried out without
coupling of the load.
