11.6 Load Monitor and
Process Protection [400]
11.6.1 Load Monitor [410]
The monitor functions enable the AC drive to be used as a
load monitor. Load monitors are used to protect machines
and processes against mechanical overload and underload,
e.g. a conveyer belt or screw conveyer jamming, belt failure
on a fan and a pump dry running. See explanation in
Chapter 7.5 page 67.
Alarm Select [411]
Selects the types of alarms that are active.
Communication information
Alarm Trip [412]
Selects which alarm must cause a trip to the AC drive.
Communication information
Ramp Alarm [413]
This function inhibits the (pre) alarm signals during
acceleration/deceleration of the motor to avoid false alarms.
Communication information
Alarm Start Delay [414]
This parameter is used if, for example, you want to override
an alarm during the start-up procedure.
Sets the delay time after a run command, after which the
alarm may be given.
• If Ramp Alarm=On. The start delay begins after a RUN
command.
• If Ramp Alarm=Off. The start delay begins after the
acceleration ramp.
Communication information

Default: Off
Off 0 No alarm functions active.
Min 1
