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 (A/V) or it
may be set as a percentage of the ASD rating. The nameplated FLA of the
motor may be entered directly when Amps is selected as the unit of
measurement (see
F701
to change the display unit).
The Motor 3 Overload Protection Level setting will be displayed in Amps if
the EOI display units are set to A/V 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
parameter 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 (see
Table 8 on pg.
For proper motor operation, the Base Frequency should be set for the
nameplated frequency of the motor.
Base Frequency Voltage 4
Program Motor Motor Set 4
The Base Frequency Voltage 4 is the Motor 4 output voltage at the Base
Frequency 4 (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 (see
Table 8 on pg.
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 (see
