Motor Overload Protection Level 4

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 Current/Voltage Units Setup ( F701) to change the display
unit).
Motor Overload Protection Level settings (1 – 4) will be displayed in Amps
if the EOI display units are set to V/A rather than %.

Special Parameters
This parameter may be used in the Constant Torque or the Variable Torque
modes only and should be adjusted gradually to improve the application-
specific torque requirements. The
Manual Torque Boost 1 setting ( F016 ) may
be adjusted to improve the low-frequency torque performance.
Note: The Torque Boost setting should be adjusted gradually before
attempting performance corrections using this parameter.

V/f Five-Point Setting
The V/f Five-Point 1 Frequency setting establishes the frequency that is to be
associated with the voltage setting of F191 ( V/f Five-Point 1 Voltage ).
The V/f Five-Point settings define a custom volts per hertz relationship for the
startup output of the ASD.
To enable this function, set the V/f Pattern ( F015 ) selection to V/f Five-Point
Setting .
V/f Curves may be useful in starting high inertia loads such as rotary drum
vacuum filters.
