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
regulations, 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
established, 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 disconnected
before removing the motor and mains plugs.

AKD 2800 Quick Setup

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
simultaneously to give access to all parameters.

Warning against unintended start

The motor can be brought to a stop
by means of digital commands, bus
commands, references or local stop,
while the frequency converter is connected to
mains. If personal safety considerations make
it necessary to ensure that no unintended start
occurs, these stops are not sufficient.
While parameters are being programmed, 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 temporary overload, a fault in the supply mains
or a fault in the motor connection ceases.
