OVLD TIME OUT and OVLD START LEVEL
These two parameters are used to define the
overload curve.
The user can adjust the motor overload
parameters. Three overload curves are shown
in the examples below. Curve #1 is the default
motor overload curve.

curve #1 110% 60 sec

curve #3 120% 70 sec
Motor Overload Parameters
When the motor usage exceeds the user
defined motor overload curve, the drive will
declare a motor overload alarm.
The drive will only declare a motor overload
alarm and the user is responsible for taking
appropriate action to protect equipment.
The motor overload alarm can also be
assigned to a logic output. See configuration
sub-menu items, C3.
The drive can also be configured so that a
motor overload event declares a Fault, which
will automatically cause the drive to stop. If
this is desirable, the following needs to be
completed:
solid state relay or relay coil is configured
to MTR OVERLOAD
logic input configured to EXT FAULT
wire the EXT FAULT logic input terminal to
the to MTR OVERLOAD relay output
terminal
wire one side of the normally open relay to
+24V (TB1-11 or TB1-46)
With the above set-up, the drive will then
declare an External Fault on a motor overload.
