ONFIGURATIONS
To control the shaft position through AZ3s, mode of operations must be set to 1 as defined in DS402
specification.
Target position is the position set point and can be modified through CAN or Modbus, analog inputs
(refer to chapter 4.4) and digital inputs (refer to chapter 4.5).
Soft min position limit and Soft max position limit define the absolute position limits for the Target
position and the Position actual value. If the shaft moves over these limits power stage is disabled.
Min position range limit and Max position range limit shall limit the numerical range of Target
position. This parameters are summarized in the position ramp block in the image below.
Position actual value is the feedback of the actual position. Setting Invert position feedback to 1, it
is possible to invert the value read in Position actual value.
Profile acceleration, Profile deceleration and Max profile velocity have the same functions that in
Profile velocity mode. Profile velocity defines the operating speed used in order to reach Target
position.
