135 – rw 0.20 - 230/500 V Nominal motor voltage 230
(￫ Motor rating 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 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.
P-09 137 – rw 25 - 500 Hz Rated motor frequency 50.0
(￫ Motor rating plate)
Note:
The parameter value will automatically be used as the cut-off
frequency for the V/Hz characteristic curve as well.
P-11
139 ✓ rw 0.00 - 20.0 % Voltage amplification 3.0
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.
