6.1.2 Basic Set-up Parameters

0-02 Motor Speed Unit
Option: Function:
NOTICE!
This parameter cannot be adjusted while the
motor is running.
The display showing depends on settings in
parameter 0-02 Motor Speed Unit and 0-03 Regional
Settings. The default setting of parameter 0-02 Motor
Speed Unit and 0-03 Regional Settings depends on
which region of the world the adjustable frequency
drive is supplied to, but can be re-programmed as
required.
NOTICE!
Changing the Motor Speed Unit resets certain
parameters to their initial value. It is
recommended to select the motor speed unit
before modifying other parameters.
[0] RPM Selects display of motor speed variables and
parameters (i.e., references, feedback and limits) in
terms of motor speed (RPM).
[1] Hz Selects display of motor speed variables and
parameters (i.e., references, feedback and limits) in
terms of output frequency to the motor (Hz).
0-50 LCP Copy
Option: Function:
NOTICE!
This parameter cannot be adjusted
while the motor is running.
[0] No copy
[1] All to LCP Copies all parameters in all set-ups from
the adjustable frequency drive memory
to the LCP memory.
[2] All from LCP Copies all parameters in all set-ups from
the LCP memory to the adjustable
frequency drive memory.
[3] Size indep. of LCP Copy only the parameters that are
independent of the motor size. The latter
selection can be used to program several
adjustable frequency drives with the
same function without disturbing motor
data.

Select the torque characteristic required.
VT and AEO are both energy saving operations.
Motor shaft output provides constant torque
under variable speed control.
Motor shaft output provides variable torque
under variable speed control. Set the variable
torque level in 14-40 VT Level.
Automatically optimizes energy consumption by
minimizing magnetization and frequency via
14-41 AEO Minimum Magnetization and
14-42 Minimum AEO Frequency.
The function provides a constant power in the
field weakening area.
The torque shape of motor mode is used as a
limit in the generatoric mode. This is done to
limit the power in generatoric mode that
otherwise becomes considerable larger than in
motor mode, due to the high DC link voltage
available in generatoric mode.
P shaft W = ω mech rad / s × T Nm
