RESET TYPE 1 - DESCRIPTION
When the procedure is activated (b94.12=1) the axis is brought to the speed programmed in
Pr4 (Pr5=Pr4); the axis is then brought to zero speed (Pr5=0) on the positive front of the
homing sensor signal; after 150ms with the motor stopped parameters Pr61:60 and Pr63:62
are reset, the position loop is enabled by setting b40.2=1, and command b94.12 is reset. The
homing sensor signal must be maintained active in high status for the entire duration of the
motor stopping phase.
If the homing sensor is already engaged when the procedure is activated, the axis moves at the
speed programmed in Pr4 but in the opposite direction until the homing sensor is freed; At
this point the procedure continues as described above.
RESET TYPE 2 - DESCRIPTION
When the procedure is activated (b94.13=1) the axis is brought to the speed programmed in
Pr4 (Pr5=Pr4); the axis is then brought to zero speed (Pr5=0) on the positive front of the
homing sensor signal; after 150ms with the motor stopped parameters Pr61:60 and Pr63:62
are programmed with the value of parameter Pr28, the position loop is enabled by setting
b40.2=1, and command b94.13 is reset. The homing sensor signal must be maintained active
in high status for the entire duration of the motor stopping phase.
If the homing sensor is already engaged when the procedure is activated, the axis moves at the
speed programmed in Pr4 but in the opposite direction until the homing sensor is freed; at this
point the procedure continues as described above.
8.2.3
Backup
If it is necessary to keep the control electronics of the converter powered up even when there
is no current, for example, to keep the encoder simulation operating, it is sufficient to keep
power on terminals 24 and 48 of the X4.
8.2.4 Speed adjustment
In the operating mode default conditions (Pr31=0), the drive adjusts the motor in speed based
on the reference value.
The reference orign can be selected with the main block parameters, between analogue
(external potentiometer), internal (digital), or external pulse string.
