5.15 Directional lock
5.15.1 Function
The directional lock function blocks the movement of the drive in one or both directions. The direction-
al lock is triggered automatically in the following cases:
Directional lock trigger Description
The actual position value has
reached or exceeded the para-
meterised software limit posi-
tion.
A hardware limit switch has
been triggered.
Movement in the corresponding direction is automatically
blocked. The closed-loop controller only allows movements in the
opposite direction.
The directional lock remains active until the actual position value
is in the valid range again or the directional lock is deactivated via
parameter Px.10351.
Tab. 340 Directional lock
If a directional lock is requested during an error response (stop ramp), for example to monitor the soft-
ware limit position, it is only activated once the stop ramp has been terminated.
