1.12 ALARM BLOCK CONFIGURATIONS (ALARM CONFIG)
This chapter describes how to control the several Drive alarms.
1.12.1
Alarms
The word “alarms” refers to two different error families. They are:
·
Errors due to a wrong setting of the Drive parameters
·
Intervention of the Drive protection systems
The former occur during the drive configuration phase and state, for example, the presence of parameter sets
which can not be combined or which overcome the Drive limits.
The solution is checking the entered parameters and resetting them if possible.
The latter are indications about the intervention of protection systems, which could cause the Drive stop. In this
case the alarm cause has to be found and reset.
1.12.2
Alarm State
The alarm cause can be:
·
Active
·
Non-active
The alarms have displayed via the Alarm List . It shows all the occurred alarms, both if they are due to protec-
tions and to errors on the overcome limit values.
In order to disappear from the alarm list they have to be recognized. The recognition is possible only if the alarm
is no more active. The alarms are automatically recognized after two minutes.
The drive State Machine, controls the drive running and starting, accounting for protection & alarming, command
sequence, and reset status.
The waiting phase for the State Machine reset is showed in the Alarm List as Sequencer.
