The drive can then be restarted by activating the necessary bits to give a normal start.
Sequencer latching enabled (Pr 6.40=1)
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 one of the following conditions occurs.
1. Run forward, Run reverse and Run sequencing bits all zero after the latches
2. OR Not stop sequencing bit is zero
3. OR the drive is disabled via Pr 6.15 or Pr 6.29
4. OR Run forward and Run reverse are both active and have been for 60ms.
5. The drive is in the UV state.
The drive can then be restarted by activating the necessary bits to give a normal start. Note that Run forward and Run reverse together will reset the
stop key condition, but the latches associated with Run forward and Run reverse must then be reset before the drive can be restarted. It should be
noted holding the Run key and pressing the Stop key to reset the drive without stopping does not apply unless keypad reference mode is selected.
Setting this parameter to 0 will disable the drive. It must be at 1 for the drive to run.
When this parameter is set up correctly for the local currency, Pr 6.26 will give an instantaneous read out of running cost.
If this parameter is one the energy meter (Pr 6.24 and Pr 6.25) is reset and held at zero.
