Start Permissives
Absolute Min Mode
This mode regulates to the smallest absolute value of torque or speed, when the
torque reference and torque generated from the speed regulator are compared.
Position/Speed Profile Mode
The drive operates as a speed or position regulator as determined by the Profile Step
parameters (720-877) and Setup parameters (705-719). See "Position Indexer/
Speed Profiler" on
page 61
for complete description of this function.
Start Permissives
Start permissives are conditions required to permit the drive to start in any mode –
run, jog, auto-tune, etc. When all permissive conditions are met the drive is
considered
read
y to start. The ready condition is available as the
drive ready
status.
Permissive Conditions
1.
No faults can be active.
2.
No type2 alarms can be active.
3.
The TB Enable input (if configured) must be closed.
4.
The DC bus precharge logic must indicate it is a start permissive.
5.
All Stop inputs must be negated (See special Digital Inputs Stops Configuration
issues below).
6.
No configuration changes (parameters being modified) can be in-progress.
If all permissive conditions are met, a valid start, run or jog command will start the
drive. The status of all inhibit conditions, except for item
6
above, are reflected in
[Start Inhibits].
