In parameter 002 Local/remote control, the fre-
quency converter mode can be selected as Remote
operation [0], i.e. via the control terminals, or Local
[1], i.e. via the control unit.
Set the control location to Local [1].
Local/remote operation = Local [1] Par. 002
Set the motor speed by adjusting the Local refer-

Local reference Parameter 003
Motor start
Press [Start] to start the motor. Set the motor speed
by adjusting parameter 003 Local reference.
Check whether the direction of rotation of the motor
shaft is clockwise. If not, exchange any two phases
on the motor cable. Press [STOP/RESET] to stop
the motor. Press [QUICK MENU] to return to display
mode.
[QUICK MENU] + [+] keys must be pressed simulta-
neously to give access to all parameters.
Safety regulations
The voltage of the frequency converter
can be fatal whenever it is connected to
mains. Incorrect installation of the motor
or the frequency converter may lead to damage to
the equipment, serious personal injury or death.
Consequently , the provisions of this Quick Setup, as
well as national and local rules and safety regula-
tions, must be complied with.
Touching the electrical parts may be fatal, even after
the equipment has been disconnected from mains:
wait at least 4 min.
1. The mains supply to the frequency converter must
be disconnected if repair work is to be carried out.
2. The [STOP/RESET] key on the control panel of
the frequency converter does not disconnect the
mains supply and is thus not to be used as a
safety switch.
3. Correct protective earthing of the unit must be es-
tablished, the user must be protected against
supply voltage, and the motor must be protected
against overload in accordance with applicable
national and local regulations.

4. The earth leakage current is higher than 3.5 mA.
5. Protection against motor overload is not included
in the factory setting. If this function is required,
set parameter 128 Motor thermal protection to
data value ETR Trip or ETR Warning.
6. Check that the mains supply has been discon-
nected before removing the motor and mains
plugs.
Warning against unintended start
The motor can be brought to a stop
by means of digital commands, bus com-
mands, references or local stop, while the
frequency converter is connected to mains. If per-
sonal safety considerations make it necessary to
ensure that no unintended start occurs, these stops
are not sufficient.While parameters are being pro-
grammed, the motor may start. Consequently, the
stop key [STOP/RESET] must always be activated,
following which data can be modified.A motor that
has been stopped may start if faults occur in the
electronics of the frequency converter, or if a tempo-
rary overload, a fault in the supply mains or a fault in
the motor connection ceases.
