NOTE
It is important to set motor parameters in 1-2* correctly,
since these form part of the AMA algorithm. An AMA must
be performed to achieve optimum dynamic motor
performance. It may take up to 10 min, depending on the
power rating of the motor.
NOTE
Avoid generating external torque during AMA.
NOTE
If one of the settings in parameter group 1-2* is changed,
parameters 1-30 to 1-39, the advanced motor parameters,
will return to default setting.

6.1.2 Basic Setup Parameters
0-02 Motor Speed Unit
Option: Function:
The display showing depends on settings in
0-02 Motor Speed Unit and 0-03 Regional Settings. The
default setting of 0-02 Motor Speed Unit and
0-03 Regional Settings depends on which region of
the world the frequency converter is supplied to, but
can be re-programmed as required.
NOTE
Changing the Motor Speed Unit will reset certain
parameters to their initial value. It is
recommended to select the motor speed unit
first, before modifying other parameters.
[0] RPM Selects display of motor speed variables and
parameters (i.e. references, feedbacks and limits) in
terms of motor speed (RPM).
0-02 Motor Speed Unit
Option: Function:
[1] * Hz Selects display of motor speed variables and
parameters (i.e. references, feedbacks and limits) in
terms of output frequency to the motor (Hz).
NOTE
This parameter cannot be adjusted while the motor is
running.
0-50 LCP Copy
Option: Function:
[0] * No copy
[1] All to LCP Copies all parameters in all set-ups from
the frequency converter memory to the
LCP memory.
[2] All from LCP Copies all parameters in all set-ups from
the LCP memory to the frequency
converter memory.
[3] Size indep. from
LCP
Copy only the parameters that are
independent of the motor size. The latter
selection can be used to programme
several frequency converters with the
same function without disturbing motor
data.
[4] File from MCO
to LCP
[5] File from LCP to
MCO
NOTE
This parameter cannot be adjusted while the motor is
running.
1-03 Torque Characteristics
Option: Function:
Select the torque characteristic required.
VT and AEO are both energy saving
operations.
[0] * Constant
torque
Motor shaft output provides constant torque
under variable speed control.
[1] Variable
torque
Motor shaft output provides variable torque
under variable speed control. Set the
variable torque level in 14-40 VT Level.
[2] Auto Energy
Optim.
Automatically optimises energy consumption
by minimising magnetisation and frequency
via 14-41 AEO Minimum Magnetisation and
14-42 Minimum AEO Frequency.
NOTE
This parameter cannot be adjusted while the motor is
running.
