2.8.11.22 Positioning via sensor or limit switch
This function is used for managing positioning using position sensors or limit switches linked to logic inputs or
using control word bits:
• Braking
•
Stop
The action logic for the inputs and bits can be configured on a rising edge (change from 0 to 1) or a falling edge
(change from 1 to 0). The example below has been configured on a rising edge:
Forward run command
Reverse run command
[Slowdown forward]
[Stop FW limit sw.]
Speed
[Low speed]
(LSP)
0
0
0
0
0
The slowdown mode and stop mode can be configured.
The operation is identical for both directions of operation. Slowdown and stopping operate according to the same
logic, described below.
Example: Forward slowdown on rising edge
• Forward slowdown takes place on a rising edge (change from 0 to 1) of the input or bit assigned to forward
slowdown if this rising edge occurs in forward operation. The slowdown command is then memorized, even
in the event of a power outage. Operation in the opposite direction is authorized at high frequency. The
slowdown command is deleted on a falling edge (change from 1 to 0) of the input or bit assigned to forward
slowdown if this falling edge occurs in reverse operation.
• A bit or a logic input can be assigned to disable this function.
•
Although forward slowdown is disabled while the disable input or bit is at 1, sensor changes continue to
be monitored and saved.
