Table 14: Motor A5 Submenu
OVLD START LEVEL
(Motor Overload Start Level)
This parameter defines maximum current at
which motor can run continuously. This
parameter is also one of the two parameters
that define the motor overload curve.
The motor overload parameters can be
adjusted by the user. The following two
parameters are used to define the motor
overload curve.

motor current overload start level (OVLD
START LEVEL(A5)) parameter

motor current time out (OVLD TIME
OUT(A5)) parameter
Three overload curves are shown. Curve #1 is
the default motor overload curve. The
parameter settings that define the three
overload curves are shown.

Motor Overload Parameters
When the motor had exceeded the user
defined motor overload curve, the drive will
declare a motor overload alarm.
The motor overload alarm can also be
assigned to a logic output.
Under the POWER DATA display sub-menu,
the MOTOR OVERLOAD (D2) value displays
the percentage of motor overload trip level
reached. Once this value reaches 100% the
motor has exceeded its user defined overload
curve and a motor overload alarm is declared
by the drive.
The drive will only declare a motor overload
and the user is responsible for action.
But, if the user wants the drive to declare a
fault on a motor overload the following need to
be completed:

logic output configured to MTR
OVERLOAD

logic input configured to EXT FAULT

wire the EXT FAULT logic input terminal to
the MTR OVERLOAD logic output terminal

wire the logic input common terminal to the
logic output common
With the above set-up, the drive will then
declare an External Fault on a motor overload
(Motor Ovrld Sel) C1
This parameter selects the action to be taken
by the drive when declareing a Motor
Overload.

Alarm
– the drive only declares a motor
overload and the user is responsible for
action

Flt immediate
– the drive will immediately
declare a fault and turn-
off the drive’s
output

Fault at stop
– the drive will delay declaring
a fault until the run command is removed
