6.3.2 87-Hz Characteristic curve
In order to have the motor from  Figure 16, page 39 run with an 87-Hz
characteristic curve, the parameters need to be configured as follows:
The motor must be in a delta configuration for this purpose. When this setup
is used, the motor will have a motor voltage of 230 V at a frequency of 50 Hz
and a motor voltage of 400 V at a frequency of 87 Hz. The field-weakening
range will start above 87 Hz.
Table 12 below shows which motor is needed for which mains voltage.

Pay attention to the mains voltage and the type of circuit in the stator
winding!
Note:
This parameter has a direct influence on the V/Hz characteristic curve
(e.g. operation with the 87-Hz characteristic curve). This must be espe-
cially taken into account in the case of values (P-07) that deviate from
the variable frequency drive's rated operational data (U
LN
= 100%). This
may cause the over-excitation of the motor and thus lead to an
increased thermal load.
