Control action 4, move axis – negative direction
Control signals:
Direction minus [R–]
Velocity level [BP]

Velocity level [BP]
9-14
Level
The user initiates a [BA] command.
The module returns [BAR] and [SFG].
When [SFG] and [AF] are active, [R+] is actuated.
The axis cancels the [SFG] and outputs messages [BL] and
[FR+]
[R+] is canceled
When the axis has come to a standstill by way of the decel-
eration ramp, the [BL] and [FR+] messages are canceled and
[SFG] is activated.
Before the axis comes to a standstill, it is possible to define a
new direction "through start".
[R–] is actuated in combination with velocity level 2.
The axis travels at velocity level 2, and returns [BL] and
[FR–]. The [SFG] signal is canceled.
A switchover from [level 2 to level 1] causes a dynamic tran-
sition between velocity levels 1 and 2.
