Electronic Thermal Protection #2
Program
Motor Parameters
Motor Set #2
The
Motor #2 Electronic Thermal Protection
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
to change the display unit).
Electronic Thermal Protection
settings
(#1 – #4) will be displayed in
Amps
if
the keypad display units are set to
V/A
rather than
%
.

Motor #3 Base Frequency
Program
Motor Parameters
Motor Set #3
The
Motor #3
Base Frequency
setting is the frequency at which the output
voltage of the ASD reaches its maximum setting. The
Maximum Output
Voltage
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.
Direct Access Number — F174
Parameter Type —
Numerical
Factory Default —
60.0
Changeable During Run —
Yes
Minimum — 25.0
Maximum — 299.0
Units — Hz
Motor #3 Max Output Voltage
Program
Motor Parameters
Motor Set #3
The
Motor #3 Maximum Output Voltage
is the
Motor
#3
output voltage at
the
Base Frequency
). 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 (
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.
Direct Access Number — F175
Parameter Type —
Numerical
Factory Default — (ASD dependent)
Changeable During Run —
Yes
Minimum — 0.0
Maximum — 600.0
Units — Volts
Motor #3 Torque Boost
Program
Motor Parameters
Motor Set #3
The
Motor #3 Torque Boost
function is used to increase the low frequency
torque for high inertia loads by increasing the output voltage at frequencies
below ½ of the
#3
Base Frequency
setting
(
).
See parameter
(
Motor #1 Torque Boost
) 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.
Direct Access Number — F176
Parameter Type —
Numerical
Factory Default — (ASD dependent)
Changeable During Run —
Yes
Minimum — 0.0
Maximum — 30.0
