4.4.2 Motion block data
The data of each motion block is saved separately. The motion block data consist of
values for:
Target
Position
Speed
Acceleration
Deceleration
Ramp rise times
Logic
Next motion block
- Event
- Interruption Event
- Delay
Digital signal
Digital signals for indication
of status of motion orders
4.4.2.1 Target position
Parameter Target Position/Distance 1202 defines the distance to be covered.
The meaning of the parameter depends on parameter
Motion Mode 1208.
In
Motion Mode 1208 = "0 – absolute", an absolute target position is approached,
referred to the reference position.
In
Motion Mode 1208 = "1 – relative", a distance in relation to the current position
or the last target position is covered.
If the last position was reached via the JOG function, the value of the parameter is a
relative position relating to the current position (distance). However, if the last posi-
tion was selected as a result of a motion command, the value indicates a position in
relation to the last target position (distance).

Note: The target position / distance must be within the range of the software
limit switches in order to be able to start a motion order.
4.4.2.2 Speed
The target position is approached at the value of parameter Speed 1203. The dis-
tance to the target position and the parameterized acceleration and deceleration
determine if the speed is reached.
Parameter Setting

Note:
In the operation modes with electronic gear (Parameter

1208), the settings for parameter Speed 1203 do not have any effect.
The speed is defined by the master.
Parameter Act. Speed 1107 indicates the current speed in unit [u/s].
