ADJUSTMENT FREQUENCY
This parameter in conjunction with parameter 2610 V/F CHARACTERISTIC
ADJUSTMENT VOLTAGE sets a frequency point at which the voltage set
in parameter 2611 V/F CHARACTERISTIC ADJUSTMENT FREQUENCY
is applied to the motor. Care must be taken to avoid overheating and
damaging the motor when using this feature. Refer to section 12.5

Voltage
The V/f characteristic is defined by several parameters as follows:
Parameter
9905
: Motor Rated Voltage
Parameter
9907
: Motor Rated Frequency
The voltage set in parameter
9905
is applied to the motor at the frequency
set under normal operating conditions, the voltage is linearly reduced at
any point below the motor rated frequency to maintain a constant motor
torque output as shown by the line ‘A’ on the graph.
By using parameters parameter
2610
and
2611
, the voltage to be applied
at a particular frequency can be directly set by the user, thereby altering
the V/F characteristic.
Reducing the voltage at a particular frequency reduces the current in the
motor and hence the torque and power, hence this function can be used
in fan and pump applications where a variable torque output is desired by
setting the parameters as follows:
Parameter
2610
=
9905
/ 4
Parameter
2611
=
9907
/ 2
This function can also be useful if motor instability is experienced at
certain frequencies, if this is the case increase or decrease the voltage
(Parameter
2610
) at the speed of instability (Parameter
2611
).
For applications requiring energy saving, typically HVAC and pumping,
the energy optimizer (Parameter
2601
) parameter can be enabled. This
automatically reduces the applied motor voltage on light load.

FAULT FUNCTIONS
Programmable protection functions
3005
THERMAL OVERLOAD
Enables the drive electronic thermal overload protection. Caution, it is
recommended that an alternative means of protecting the motor from
thermal overload is used (e.g. PTC thermistor) if
3005
is disabled.
Press the Navigate key briefly to switch between Index 1 and 2. Then use
the UP or DOWN arrow to adjust the value within each Index (Index 1 is
displayed first).
0
VALUE RETENTION
Index 1
0: DISABLED
1: ENABLED
Drive retains the motor thermal overload value following an input power
cycle.
THERMAL PROTECTION
Index 2
0: DISABLED
1: ENABLED
Enables the motor thermal over protection. When the motor thermal
overload accumulator reaches 100%, the drive will fault on a
0009
trip.
