The converters of the DV-300series contain extensive monitoring functions. The effect of possible alarms on the
behaviour of the drive are defined in the PROG ALARMS submenu:
- Saving of alarm status
- How the drive is to react to the alarm
- Indication via the relay between terminal 35 and 36 (central alarm). The switch conditions for the relay can
be defined with the Ok relay func parameter in the CONFIGURATION menu.
- Automatic restart
- Failure reset
For some alarms, the behaviour of the drive can be configured separately. All alarms can also be assigned to a
freely programmable digital output.

The parameters required to configure the alarm are shown in Table in Section 10 of the manual.
Activity
Warning
The alarm does not cause reaction of the drive. A warning mes-
sage can be output via a digital output. When the drive is dis-
abled, it will not restart until the failure has been canceled.
Disable drive
The alarm causes the immediate disabling of the converter. The
motor runs to an uncontrolled stop.
Quick stop
When the alarm occurs, the drive stops according to the ramp set in
the RAMP / QUICK STOP menu. The converter is then disabled.
Normal stop
When the alarm occurs, the drive stops according to the ramp
set. The converter is then disabled.
Curr lim stop
When the alarm occurs, the converter brakes with the maximum
