Mode Bit 0 = 1) must be switched on and the revolutions to be run that are set must be
sufficiently large to avoid a reversal of direction.
m Target mode 8:
Absolute positioning on the shortest path to the defined angle
Example 1:
Current target position = 1000 5555
hex
Z118.9– Target position = 5000 AAAA
hex
High Word not relevant
AAAA
hex
- 5555
hex
= 5555
hex
less than 8000
hex
shortest path in positive direction
The new absolute target position is 1000 AAAA
hex
Example 2:
Current target position = 1000 5555
hex
Z118.9– Target position = 5000 FFFF
hex
High Word not relevant
AAAA
hex
- FFFF
hex
= AAAA
hex
greater than 8000
hex
shortest path in negative direction
The new absolute target position is 0FFF FFFF
hex
m Target mode 9:
CANopen Mode
The target indication occurs in Parameter Z118.16– Relative Target Position and the
differentiation whether this is an absolute or relative target entry occurs through Bit 6
of the Z108.1– control word.
With absolute target entries, a range offset of 2
31
increments is included in the calcu-
lation and the number range is interpreted with applied leading signs.
m Target mode 10:
The indication whether the target is absolute or relative (in relation to the last target) is
determined through Bit 6 of the control word. If Bit 6 is set while the edge of "New Set
Value" is rising, the target specification is relative. If Bit 6 is cleared, the target specifi-
cation is absolute.
The target is always determined through Parameter Z118.9– Positioning Target Posi-
tion, and with a relative target entry the value is treated with applied leading signs.
m Target mode 11:
This mode can be applied at axes on which an endless moving (rotational axis appli-
cation) is desired and the target position should be preset in modulo format. The trans-
lation of a between connected transfer element (e.g. gear) is taken into account via the
definition of the range of modulo values (Z118.20– Modulo value).
In this mode the controller calculates the shortest way to the target position itself.
If in the target position a value is entered which is greater or equal than the modulo
value, the error 912 will be output at start and it will be not started.
