msg : The message has been sent to the alarm list and to the alarm config list.
State Machine commands : A change in the drive state has been forced (alarm
intervention).
Status: The active alarm signal is immediately set; it is reset when the alarm is nmore
present and the state machine is not in an alarm condition.
Alarm configurations : Restart
With this parameter it is possible to enable the automatic start after the alarm cause has
been removed.
0 => Off
1 => On
Alarm configurations : Restart Time
With this parameter it is possible to set a period of time, within which the alarm state has
to be removed, in order to perform an automatic start.
Alarm configurations : Hold Off Time
With this parameter it is possible to set the period of time, in which a specific situation
has to remain active (it has to persist) in order to be considered an alarm situation.
It is possible to set a millisecond period of time, in which the Drive does not recognize the
alarm state. Therefore, the alarm is recognized only if it persists for a period longer than
the set “Hold off time”.
Regulation Alarm Reset
When a regulation alarm intervenes, the Drive reaches the alarm state. Such alarm state
can be reset when the alarms are no more active and the user performs a Reset Alarm.
command Transition 0=>1.
By using the Fault reset src source, it is possible to select the origin of the “reset”
command signal (for example a command via the terminal strip through a digital Input).
How to perform a “Reset Alarm” command:
> Via the keypad: by pressing the red key
> Via the terminal strip: connect the Fault reset src Pin to a digital input,
transition 0=>1.
> Via Digital (Serial . Bus . Dgfc/APC): connect the Fault reset src pin to a bit of
the decomposed word and set the decomposed word, transition 0=>1.
NOTE! If the Fault reset src pin is connected to a digital input, such input has to be kept
at a low logic state. If such state is high, the first “Fault reset” command via the red
key has no effect.
