Manual Torque Boost 3
Program
Motor
Motor Set 3
The Manual Torque Boost 3 function is used to increase the low
frequency torque for high inertia loads by increasing the output voltage
at frequencies below ½ of the Base Frequency 3 setting
.
See parameter
(Manual Torque Boost 1) for an explanation of
torque boost.
This parameter is used only when the parameters for motor set 3 are
configured and selected. Motor set 3 may be selected by a properly
configured input terminal.
Note:
Not used with the W7B ASD.

Motor Overload Protection Level 3
Program
Motor
Motor Set 3
The Motor Overload Protection Level 3 parameter specifies the motor
overload current level for motor set 3. 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 (V/A) 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
Motor Overload Protection Level settings (1 – 4) will be displayed in
Amps if the EOI display attributes are set to V/A rather than
%
.

Base Frequency 4
Program
Motor
Motor Set 4
The Base Frequency 4 setting is the frequency at which the output
voltage of the ASD reaches its maximum setting. The Base Frequency
Voltage 4 is set at
This parameter is used only when the parameters for motor set 4 are
configured and selected. Motor set 4 may be selected by a properly
configured input terminal.
For proper motor operation, the Base Frequency should be set for the
name-plated frequency of the motor.
