Technology functions
Power section parameters \ technology functions \ IPOS reference travel
Reference travel is used to establish a
machine zero
to which all absolute positioning
commands refer. For this purpose, you can choose between various so-called reference
strategies index travel strategies 8626.0 reference travel type. These strategies define
appropriate travel modes, for example, to search for a reference cam. Using the refer-
ence point determined by reference travel, the machine zero point can be changed using
P900 Reference offset according to the following equation:
Machine zero = reference po reference offset
.
The speeds of the travel movements required for the reference travel type are set using
index 8624.0 reference speed 1 / index 8625.0 reference speed 2.
IPOS axis
referenced
index 8702.0
The parameter indicates whether the MOVIGEAR
®
drive was referenced.
Reference offset
index 8623.0
Reference offset (zero offset) is used to determine the machine zero (origin).
• Setting range: –(2
31
–1) – 0 – 2
31
–1
The following applies: Machine zero = reference po reference offset
The corresponding actual positions are indicated by IPOS
plus®
variables.
• H511 Actual position motor encoder
The reference offset becomes active after reference travel has been completed
successfully.
INFORMATION
For detailed information on the following parameters, refer to the "IPOS
plus®
" manual.
WARNING
Risk of injury if the drive unit starts up automatically.
Severe or fatal injuries.
• Ensure that the motor cannot start unintentionally.
• Note that modifying these parameters without knowledge of the IPOS
plus®
pro-
gram, which may be active, can cause unexpected movements and result in un-
wanted loads on the mechanical drive train. It is essential that you are familiar with
the IPOS
plus®
manual to make the setting for these parameters.
