8.6.6 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 position + 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 DRC 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 position + 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®
program, which may be active, can cause unexpected movements and result in
unwanted 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.
