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 5 on pg. 234
).
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
(
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 (see
Table 5 on pg. 234
).

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
4
Base Frequency
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
Table 5 on pg. 234
).

Motor Overload Protection Level 4
Program
Motor
Motor Set 4
The
Motor 4 Overload Protection Level
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
(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 4 Overload Protection Level
setting
will be displayed in
Amps
if
the
EOI
display units are set to
A/V
rather than
%
.
