Motor Parameters
Motor Set #1
The
Motor #1 Electronic Thermal Protection
parameter specifies the motor
overload current level for motor set #1. This value is entered as either a
percentage of the full load rating of the ASD or as the FLA of the motor.
The unit of measurement for this parameter may be set to
Amps
or it may be set
as a percentage of the ASD rating. The name-plated FLA of the motor may be
entered directly when
Amps
is selected as the unit of measurement (see
to
change the display unit).
Electronic Thermal Protection
settings
(#1 – #4) will be displayed in
Amps
if
the keypad display units are set to
V/A
rather than
