6 - 7 - 8 STATUS->ALERT:
From any status, the DGF moves automatically into the ALERT status in case of detected
malfunction. An alarm “Opt2” is forced to the drive.
It is also possible to put the DGF in an alarm condition via the serial line of the option.
NOTE: This transition disables the drive.
9 - ALERT->READY:
The transition occurs if the DGF moves to ALERT from the READY or RUN status.
This transition depends on a parameter.
By writing this parameter it is possible to program the event that allows exiting the
alert status. Possible events are :
- only by writing the status parameter
- only by the failure reset of the drive
- only by digital input
10 - ALERT->IDLE:
This transition occurs if the DGF moves to ALERT from IDLE condition. The
description at point 9 is valid also here.
11 - RUN->IDLE:
This transition is possible only by writing the status parameter.
NOTE: This transition disables the drive.
2.2.2 Alarms
When an alarm is generated, the DGF always moves to ALERT status. This forces an
alarm “Opt2” on the drive. Note that all the alarms disable the drive. There are two
types of alarms:
Alarm type 1: “simple” alarms (e.g. alarms generated from an application) . It is possible
to exit from alarm status by executing a transition 9 of the status logic.
Alarm type 2: Severe alarms or malfunctions of the DGF (e.g. hardware). It is possible
to exit this status only by resetting the DGF or switching the drive off.
The alarm code can be read through an “ERROR CODE” via serial line, by using a
HIBS program, or via the keypad.
Any DGF alarm has an alarm code and may also have an alarm cause (description).
Both kinds of information are available on local drive keypad and through the HIBS
program. When an alarm occurs while using the keypad, the following message blinks
on the keypad:
Failure
Opt2: XXXX-YYYY
XXXX = ALARM CODE is the main code
YYYY = ALARM CAUSE contains more detailed information about the alarm
