P-02 130 ✓ rw Minimum frequency / minimum speed 0
P-10 = 0 → 0 - P-01 → Hz
P-10 > 0 → 0 - P01 → min-1
The minimum output frequency / minimum speed – shown in Hz or rpm
(if P-10 > 0).
P-07
135 – rw Nominal voltage of the motor 230
Setting range: 0. 20 - 250/500 V (￫ Motor ratings plate)
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 frequency inverter
’s rated operational data (U
LN
= 100 %). This may
cause the over-excitation of the motor and thus lead to an increased
thermal load.
P-09 137 – rw Nominal frequency of the motor 50.0
Setting range: 25 – 500 Hz (￫ Motor ratings plate)
Note:
This parameter value is also automatically applied as the cut-off
frequency for the V/Hz characteristic curve.
P-11
139 ✓ rw Voltage amplification 3.0
0.00 - 20.0 %
Voltage amplification is used in order to increase the motor voltage
applied at low output frequencies so as to improve the torque at low
speeds, as well as the starting torque.
Note:
A high start voltage enables a high torque at the start.
Notice:
A high torque at low speed causes a high thermal load on the motor.
If temperatures are too high, the motor should be equipped with an
external fan.
