Issue Number: 4
Defines the scheduling rate for the POS tasks to suit the application performance and
the resource needed to run the user DPL program. The following values are defined:
Set this parameter in order for the user DPL program to automatically run at power-on/
reset. If this is changed and the new setting needs to be used on power-up ensure that
a
drive parameter save is performed.
Setting this parameter to 1 will cause the drive to trip when certain run-time errors occur
within the Second Processor user DPL program.
For more information, see section 11.1 Run-time Errors on page 112.
When this parameter is 0, the module will be reset when a drive trip is cleared. When set
to 1 the module will be unaffected by a drive trip reset (i.e. continue running)
