3.8
The parameter is required to calculate the Rho electric Z47.47– (or for synchronous mo-
tors to calculate the pole position actual value or the commutation angle actual value) be-
ing used for the field orientation.
The parameter >127.8< is in electric coordinates. The notch position mechanic (notch
position electric divided by motor pole pair number) is displayed in
Z137.4–.
With motors with an electronic type plate automatically during the encoder initialization
the notch position is mechanically read stored in the electronic type plate and on the one
hand is stored in the "Notch position mechanic" parameter
Z137.4– and on the other
hand is converted into an electric angle by means of the motor pole pair number
Z107.19– and is entered in the parameter >127.8<.
With motors without an electronic type plate the notch position must be evaluated via the
operation mode "Notch position search". After a successful search the result is entered
in the parameter >127.8<. Then the notch position electric must be stored in the
EEPROM of the controller (store parameter set).
127.9 Maximum angle
Setting of window for permitted mechanic movement at notch position search method 1.
Now the adjusting of electric angle can be initiated.
65536 Inc correspond to 360 degrees.
127.10 Angle rising
The parameter specifies the change of the angle, by which the electric angle is adjusted
at notch position search method 1.
The value 1 Inc/ms is an electric angle modification of 5.49 degrees/s.
127.11 Error limit mech. delta angle
Window setting for permitted mechanic movement before an error is released.
The parameter is used at notch position search method 1, only.
127.12 Averaging zero speed detection
This parameter is used for the standstill detection at notch position search method 1. The
higher the value is, the lower the measured motor movement may be.
Condition for standstill Z127.12– * Phi / ms < Traversing angle (Z127.9–).
This parameter is used at notch position search method 1, only.
