In addition, care must be taken that a NORD motor from the motor list (P200) is set. If a standard
4-pole NORD motor or a motor from a different manufacturer is not used, the data for the motor
parameters ((P201) to (P208)) must be adjusted to those on the motor rating plate. The stator
resistance of the motor (see P208) must be measured by the inverter and at ambient temperature. In
order to do this, parameter P220 must be set to "1".
In addition, the frequency inverter must be
parameterised so that the motor can be operated with a maximum speed of 3000 rpm. For a four-pole
motor, the "maximum frequency" must be set to a value which is smaller or equal to 100 Hz ((P105)
≤ 100). Here the maximum permissible output speed of the gear unit must be observed. In addition,
the monitoring "I²t-Motor" (Parameter (P535) / (P533)) must be switched on and the pulse frequency
set to between 4 kHz and 6 kHz.
Overview of required parameter settings:
Parameter Setting value Factory setting Description
P105
Maximum frequency
≤ 100 Hz [50]
This value relates to a 4-pole motor. On
principle, the value must only be so large that
a motor speed of 3000 rpm is not exceeded.

If a 4-pole NORD motor is used, the pre-set
motor data can be called up.

Motor data
Data according to
rating plate

If a 4-pole NORD motor is not used, the
motor data on the rating plate must be
entered here.
P218
Degree of

Determines the maximum possible output
voltage
P220
Parameter
identification
1 [0]
Measures the stator resistance of the motor.
When the measurement is complete, the
parameter is automatically reset to "0". The
value that is determined is written to P208
P504
Pulse frequency
4 kHz … 6 kHz [6]
For pulse frequencies above 6 kHz a
reduction of the maximum torque is
necessary.
P533
Factor I 2 t-Motor
< 100% [100]
A reduction in torque can be taken into
account with values less than 100 in the I²t
monitoring.
P535
I²t motor
According to motor
and ventilation
[0]
The I²t- monitoring of the motor must be
switched on. The set values depend on the
type of ventilation and the motor used. See
