Figure 9-16 Low DC bus operation
The remote LED display has a function key. When the key is pressed this parameter will be 1 otherwise it will be 0. This allows drive user
programming to access the function key.
This parameter permanently enables the Stop key on the drive such that the drive will always stop when the stop switch is pressed. If keypad mode is
selected this has no effect because the stop key is automatically enabled.
The sequencer logic has been designed so that pressing the stop key, whether the stop key is enabled or not, does not make the drive change from
a stopped to a running condition. As the stop key is also used to reset trips this means that if the stop key is pressed when the drive is tripped, the trip
will be reset but the drive will not start. This is done as follows.
Sequencer latching not enabled (Pr 6.40 = 0)
If the stop key is pressed when the stop key is enabled (Pr 6.12 = 1) or when the drive is tripped the sequencer run is removed, and so the drive stops
or remains stopped respectively. The sequencer run can only then be reapplied after at least on of the following conditions occurs.
1. Run forward, Run reverse and Run sequencing bits all zero
2. OR the drive is disabled via Pr 6.15 or Pr 6.29
