2 Safety Notice
The installation, commissioning and parameter configuration may be performed only by
qualified personnel, who have thoroughly read and understood these commissioning
instructions.
The technical documents and program versions issued by the manufacturer must always be
used for commissioning.
One must be prepared for unexpected responses by the whole drive during commissioning as
a result of incorrect settings, incorrect connection and/or defective components.
Before commencing commissioning, at least the EMERGENCY OFF functions, voltage
isolation and fall of the mechanical brake must be installed and tested.
The unauthorised removal of parts of the enclosure, improper use and incorrect installation or
operation can cause fatal or serious injury and material damage.
Pay attention before every commissioning that all persons and objects are removed from the
danger area.
The frequency converter described in these operation instructions is specially intended for use
in the lift industry. The frequency converter is to be used only for the step less speed control of
three-phase motors. The operation of other electrical consumers is not permitted and can lead
to destruction of the equipment.
Commissioning, i.e. the commencement of operation for the intended purpose, is permitted
only subject to the applicable EMC directives.
Oil lubrication in a power or force transmission systems with an oil-filled gear casing (geared
motor) or reduction gears can deteriorate during operation at low speeds. Information on the
permissible continuous speed range must be obtained from the gear manufacturer.
The motor and the rotary encoder must have the same direction of rotation. The exact phase
connection is to be taken into account on the motor terminal panel for synchronous motors in
addition to the phase sequence (rotating field).
If reactive power compensation equipment is installed in the power mains, it is to be checked
for correct function.
If earth-leakage relays are employed, their sensitivity should be 300 mA or more per converter.
The earth-leakage relays must be suitable for pulsed DC currents.
Check the required motor current at all speeds after completing commissioning (current
measurement or evaluation of terminal A6).
Check the function of the brake resistor after completing commissioning; the resistor must not
glow! Pay attention to the risks of ignition/inflammation and fire.
