Motor Current
NO
PARAMETER
DESCRIPTION
SCALE
INCREMENT
DEFAULT
2
Motor current
Motor nominal current
< 60% of CT
ratio
Minimum 2A
10A
This parameter sets the motor full load stator current.
The value to be used is the stator current related to the mechanical power for the specific duty.
CAUTION
DO NOT EXCEED THE MOTOR NAMEPLATE
VALUE FOR THE APPLICABLE DUTY.
Note
This value should be determined during the
design phase. This value is to be used by the
thermal model to calculate overload conditions.

3
Overload class
Thermal overload class
type
5 or 10
-
5
This parameter selects the Class of overload that the thermal model uses as a reference.
Class 5:
Trip if stator current exceeds three times motor full load current for a period exceeding 17 sec.
Class 10:
Trip if stator current exceeds three times motor full load current for a period exceeding 34 sec.
