Assignment
- - - - A A A A t t t t r r r r Automatic restart, after locking on a fault, if the fault has disappeared and
the other operating conditions permit the restart. The restart is performed by
a series of automatic attempts separated by increasingly longer waiting
periods : 1 s, 5 s, 10 s, then 1 min for the following attempts. If the restart
has not taken place after 6 min, the procedure is aborted and the speed
controller remains locked until it is powered down then powered up. The
following faults permit this function : OHF, OLF, USF, ObF, OSF, PHF, OPF,
SLF. The speed controller fault relay remains activated if this function is
active. The speed reference and the operating direction must be
maintained.
This function can only be used in 2-wire control (tCC = 2C).
- Check that any accidental start does not present any danger
to personnel or equipment
- no : Function inactive
- YES : Function active
- USF : Function only active for the USF fault
- - - - O O O O P P P P L L L L Enables the motor phase failure fault.
- no : function inactive
- YES : function active (motor phase loss detection)
- OAC: activation of the function which manages the presence of a down-
stream contactor
- - - - I I I I P P P P L L L L Enables the line supply phase failure fault.
no : function inactive. YES : function active.
This parameter does not exist on the ATV28HU09M2, U18M2, U29M2 and
U41M2 for a single phase line supply.
The fault is only detected if the motor is on-load (around 0.7 times the
nominal power). At low load, single phase operation does not cause
damage.
- - - - S S S S t t t t P P P P Controlled stop on loss of line supply :
Controls the stopping of the motor when there is a loss of line supply,
following a ramp which which can be adjusted via FLG (see SET adjust
menu page 88) according to the kinetic energy restored.
no : function inactive. YES : function active.
