NORDAC FLEX (SK 200E ... SK 235E) – Users Manual for Frequency Inverters
80 BU 0200 en-3118
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.
P200
Motor list
motor power
[0]
If a 4-pole NORD motor is used, the pre-set
motor data can be called up.
P201 – P208
Motor data
Data according to
rating plate
[xxx]
If a 4-pole NORD motor is not used, the
motor data on the rating plate must be
entered here.
Degree of
modulation
≥ 100% [100]
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
B1091-1
