Functional Description
The positioning of the spindle is started via
S-0-0152, C0900 Position
spindle command
. During the execution of the command the controller
ignores the current command value of the active operating mode.
The presetting for the kind of positioning and motion of the spindle
towards the target position in made in
S-0-0154, Spindle position
parameter
.
The spindle can be positioned at
•
the absolute target position or
•
the relative target position.
When "absolute target position" was set, the value from parameter
S-0-0153, Spindle angle position
is accepted, at the start of spindle
positioning, as the target position effective in the drive (
S-0-0430,
Effective target position
).
When "relative target position" was set, the target position (S-0-0430)
effective in the drive at the start of spindle positioning is generated by
addition of the current actual position value and the value from
S-0-0180,
Spindle relative offset
.
In the case of modulo scaling of position data, it is possible to choose
between the following directions of motion for spindle positioning:
•
clockwise
rotation
•
counter-clockwise
rotation
•
shortest
distance
The allowed maximum velocity during the spindle positioning process is
entered in parameter
S-0-0222, Spindle positioning speed
.
The maximum acceleration or deceleration during the spindle positioning
process is determined by parameter
S-0-0372, Drive Halt acceleration
bipolar
.
For spindle positioning the position control loop can be closed via the
motor encoder or the optional encoder.
