Important: The terminal strip start input then becomes another stop function and
start permissive condition:
• When the start input is open, the drive will stop and remain stopped.
• The start input must be closed to allow the drive to start.
The control source must be the terminal strip (P.000 = rE) to use this feature.
The converted analog input value, after the offset parameter (P.009) has been
applied, can be viewed in P.091 (Diagnostics Display) when P.090 (Diagnostics
Source) is set to 10. This is the value against which the stop and start threshold
values are compared to determine the appropriate input start/stop action.
G.4.1 Adjusting the Stop and Start Thresholds
The start threshold defaults to 0.33 VDC (nominally) and the stop threshold defaults to
0.20 VDC (nominally) when the Power Module is identified (P.998/P.999). These
thresholds can be viewed and adjusted using parameters P.090 (Diagnostics Source)
and P.091 (Diagnostics Display).
Setting P.090 to 11 selects the analog input stop threshold for viewing and modifying
in parameter P.091.
Setting P.090 to 12 selects the analog input start threshold for viewing and modifying
in parameter P.091.
Note that the default threshold values are not restored when P.050 (Restore Defaults)
is set to ON.
G.4.1.1 Stop Threshold Range
The default value of the stop threshold is 20 A/D counts, which corresponds to 0.20
VDC (nominal).
The stop threshold minimum value is 5 counts. The stop threshold maximum value is
1023 counts.
If the stop threshold is greater than the start threshold, the stop will take precedence.
In other words, if the analog input is less than or equal to the stop threshold, the drive
will stop regardless of the start threshold.
