Direct Access Parameter Information
W7B ASD Installation & Operation Manual
Base Frequency Voltage 4
Program Motor Motor Set 4
The Base Frequency Voltage 4 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 Correction 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.
Note:
Not used with the W7B ASD.
Manual Torque Boost 4
Program Motor Motor Set 4
The Manual Torque Boost 4 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 4 setting (F178).
See parameter
F016
(Manual Torque Boost 1) 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.
Note:
Not used with the W7B ASD.
Motor Overload Protection Level 4
Program Motor Motor Set 4
The Motor Overload Protection Level 4 parameter specifies the motor
overload current level for motor set 4. 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
Motor Overload Protection Level (1 – 4) will be displayed in Amps if the
EOI display attributes are set to V/A rather than %.
Note:
Not used with the W7B ASD.
