Motor Parameters

Motor Set #3
The Motor #3 Electronic Thermal Protection 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 F701 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 % .

Motor #4 Base Frequency
Program

Motor Parameters

Motor Set #4
The Motor #4 Base Frequency setting is the frequency at which the output
voltage of the ASD reaches its maximum setting. The Maximum Output
Voltage is set at F179 .
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.

Motor #4 Max Output Voltage
Program

Motor Parameters

Motor Set #4
The Motor #3 Maximum Output Voltage is the Motor #4 output voltage at
the Base Frequency ( F178 ). Regardless of the programmed value, the output
voltage cannot be higher than the input voltage.
The actual output voltage will be influenced by the input voltage of the ASD
and the
Supply Voltage Compensation setting ( F307 ).
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.
Direct Access Number — F179

Motor #4 Torque Boost
Program

Motor Parameters

Motor Set #4
The Motor #4 Torque Boost function is used to increase the low frequency
torque for high inertia loads by increasing the output voltage at frequencies
below ½ of the
#4 Base Frequency setting ( F178 ).
See parameter F016 ( Motor #1 Torque Boost ) for an explanation of torque
boost.
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.
