Figure 4-7: Drive Start, Stop, and Running Status when Configured for Edge Control vs. Level Control
Note that when operating from the terminal strip (rE) or a network option, an edge is required at
the start input for the following two conditions, even if P.054 = ON:
• The front panel keypad/display or OIM/CS3000 STOP key is pressed.
• After a vector self-tuning procedure.
These forced edge requirements do not apply if the control source is changed to any other value
and then back again as shown in the following example.
Using the Level Sense Start Enable Feature and the Analog Input Start/Stop Feature
In V6.06 the analog input can be configured to start and stop the drive.
Refer to P.009, P.011, P.090 and P.091 if you are using this feature and have configured the drive
to use the analog input to start and stop the drive.
The level sense start enable feature, configured with parameter P.054 (Level Sense Start Enable),
can be used with the analog input start/stop feature.
If the drive is configured for edge sense start (P.054 = 0), then the analog input must transition
from the off state to the on state while all permissive conditions are met to start the drive.
If the drive is configured for level sense start (P.054=1), the drive will start whenever the analog
input is in the on state and all permissive conditions are met. Note, however, that pressing the
STOP key on the keypad/display will require a subsequent off-state to on-state transition on the
analog input to restart the drive.
Regardless of the value in P.054 (Level Sense Start Enable), if the analog input is in the off state,
the drive will stop and remain stopped.
