Motor Overload Protection Level 2
Program Motor Motor Set 2
The Motor Overload Protection Level 2 parameter specifies the motor
overload current level for Motor Set 2. 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 %.
Base Frequency 3
Program Motor Motor Set 3
The Base Frequency 3 setting is the frequency at which the output voltage of
the ASD reaches its maximum setting. The Maximum Output Voltage is set at
F175.
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.
For proper motor operation, the Base Frequency should be set for the name-
plated frequency of the motor.
Base Frequency Voltage 3
Program Motor Motor Set 3
The Base Frequency Voltage 3 is the Motor 3 output voltage at the Base
Frequency (F174). 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 3 are
configured and selected. Motor Set 3 may be selected by a properly configured
input terminal.
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 (F174).
See F016 (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.
