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

.
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

. 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.
