Manual Setting Of Working Voltage/Frequency Characteristic - TDE MACNO MINIOPD EXP User Manual

it's no useful in that application where it's necessary to produce torque in steady state at frequency
below 1Hz (in this case we recommend to use a motor with feedback and a Vector control).
To enable the voltage-frequency control set C80=characteristic
The most easier way to set the voltage-frequency characteristic is to use the automatic procedure.
First of all set the maximum motor voltage (P64) and the maximum working speed (P65) and then set
C88=1 .
PRC_MOT_V_MAX

VF_EN_CHR_AUTOSET
Automatically the drive set the voltage-frequency characteristic in two possible way:
1. Linear way :
In this case, none characteristic points are set (P174-P175-P176-P177=0) and the maximum
operating voltage P64 is set:
2. Characteristic FLUX WEAKENING AREA:
3.
When the maximum motor frequency is greater than nominal frequency automatically is set
one characteristic point into nominal knee:

CHARACTERISTIC
Using the parameters P175 , P176 , P177 and P178 it is possible to define a three-section working
curve by points (so as to be better able to adjust to the desired characteristics).
