Remark:
Positive direction = in the direction of greater position set values
Negative direction = in the direction of lower position set values
Setting a reserve mode will generate a error message.
m Target mode 5:
Absolute positioning on defined angle in positive direction
Example:
Current target position = 1000 AAAA
hex
Z118.9– Target position = 1234 5555
hex
 High Word not relevant
 The new absolute target position is 1001 5555
hex
m Target mode 6:
Absolute positioning on defined angle in negative direction
Example:
Current target position = 3333 2222
hex
Z118.9– Target position = 1234 5555
hex
 High Word not relevant
 The new absolute target position is 3332 5555
hex
m Target mode 7:
The target input occurs in Parameter Z118.16– Relative target position. The maximum
adjusting range for each positioning procedure is ±0x7FFFFFFF
hex
.
The current actual position is used to calculate the new target position ( "flying" Po-
sitioning). The new target position is calculated as follows:
n The angle to be activated (absolute) is in the Low Word of the Relative target posi-
tion parameter.
n The revolutions to be adjusted (relative) are in the High Word of the Relative target
position parameter.
n The direction of positioning is determined using the leading sign of the "Relative Tar-
get Position" (Z118.16–) parameter.
Example:
Z121.9– Position actual value at start time = 1111 3333
hex
Z118.16– Relative target position = -294912
dez
 Leading sign negative; the value without leading sign is 48000
hex
 4 revolutions relative in negative direction, absolute angle to be adjusted is
8000
hex
 Revolutions of the new absolute target position = 1111
hex
- 4
hex
= 110D
hex
 The new absolute target position is 110D 8000
hex
For example, this target mode can use speed control (-3) or speed specification (2) into
the position target specification (1) for the online switch from the operating mode if it is
necessary to position a defined angle without a stop. The revolution part of this target
position must be without meaning. The actual speed value synchronization (
