Homing; Automatic Of Manual Start Of Homing - BONFIGLIOLI Vectron ACTIVE CUBE Series Applications Manual

Note:
4.2
When the drive is started, a defined starting position must be specified. In a homing
operation, the point of reference of the positioning operation is determined. All posi-
tioning data relates to this point of reference. Once the homing operation is started,
the drive moves until it reaches a home switch or limit switch and stops there. The
limit switches limit the motion path. The direction of movement (search direction) at
the start of the homing operation is defined by the homing mode. Additional the
reaching of a limit switch will change the direction of the drive (dependent on the
homing mode). The limit switches can also be used as the point of reference. For a
list of homing modes, refer to chapter "List of Homing Modes".
Homing can be started:
− via a digital input
− by a control word via system bus or field bus
− automatically before the start of a motion block positioning operation

Use parameter
signal, e.g. via a digital input. The signal must be present until completion of the
homing operation is signaled by logic signal "59 – Homing Done". If the start signal
is reset during a homing operation, the drive will be stopped. Homing is not com-
pleted and positioning is not possible.
The homing start condition is defined by parameter

Before a positioning operation can be started, the point of reference of
the positioning operation must be determined in a homing operation.
Otherwise, error message "F1570 – No Homing Done" will be displayed
if you try to start a positioning operation.
