Level
[R+] is actuated while the axis is traversing with [R–].
The ambiguous direction command causes the axis to stop
and [BF/FS] to be output. [FR–] and [BL] are reset.
Only when [R+] is canceled and the error is acknowledged
[BFQ/FSQ] is [SFG] actuated again and a new direction
command can be initiated.
[AF] is deactivated during the traversing movement.
The axis is stopped abruptly. [FR–] and [BL] are canceled.
Restart is defined during the traversing movement.
The axis is stopped abruptly. [FR+] and [BL] are reset.
If incremental encoders are used, resynchronization is neces-
sary. (SYN is cleared)
Only when [R+] is canceled is [SFG] reactivated.
A new [BA] 1 is preselected during the traversing movement.
The axis is stopped by way of the deceleration ramp. [FR+]
and [BL] are reset.
