P32x/P33x Motor adjustment 1/2
P320/P330 Auto-
matic adjustment
1/2
Setting range: On/off
Only effective in the "VFC" and "V/f" operating modes. The function is only useful for sin-
gle motor operation. The inverter sets

matically at each enable and stores the value. The inverter determines a basic setting
that is adequate for a great number of drive applications. The connected motor is cali-
brated during the last 20 ms of the pre-magnetization time. The motor is not calibrated
in the following cases:
•
P320/P330 Automatic adjustment 1/2 = "off"
•
P700/P701 Operating mode 1/2 = "VFC & group" or "VFC & flying start"
(page 109)
•
P323/P333 Premagnetization time 1/2
(page 101) has been reduced by more than
30 ms in relation to the proposed value.
• Operating mode "VFC-n control" is selected and
P730/P733 Brake function 1/2
(page 113) = "off"
In such cases, the set I×R value is used for calculating the winding resistance.
• On: Automatic adjustment.
• Off: No automatic adjustment.
P321/P331 Boost
1/2
Setting range: 0 – 100 %
With "VFC & group": Manual setting to increase the starting torque by increasing the out-
put voltage in the range below the base speed.
With "VFC": Manual setting is usually not required. In exceptional cases, manual setting
may be necessary to increase the breakaway torque. In this case, set max. 10 %.
P322/P332 IxR
adjustment 1/2
Setting range: 0 – 100 %
The I×R value of the matching motor is set as the factory setting.
In "VFC" operating mode, this parameter acts on the parameters of the calculated motor
model which establish the torque. An automatic setting takes place with
P320/P330 Au-
tomatic adjustment 1/2
(page 100) = "on". If set to 100 %, the output voltage of the in-
verter is increased by 50 V when the rated current of the motor flows. Manual alterations
to individual controller parameters are reserved for optimization by specialists.
