After the cause of the error has been eliminated, you have to acknowledge the error message:
l Either by using the parameterisation software, or via an edge at DIN9 (controller enable).
l If no error is active anymore, the LED goes out.
on l The drive is in the initialisation phase after the control voltage has been switched on.
l A new firmware is being installed.
Note!
The light−emitting diode "Error" constantly blinks if a fault is active:
ƒ It only displays one fault at a time.
ƒ If several faults are active at the same time, the fault that occured first is displayed.

Safety instructions
General safety and application notes for Lenze controllers
2 Safety instructions
2.1 General safety and application notes for Lenze controllers
(in accordance with Low−Voltage Directive 2006/95/EC)
For your pesonal safety
During operation, Lenze controllers (frequency inverters, servo inverters, DC speed
controllers) and their corresponding components can be live, moving and rotating
according to their degree of protection. Surfaces can be hot.
Non-authorized removal of the required cover, inappropriate use, incorrect installation or
operation creates the risk of severe injury to persons or damage to material assets.
Additional information can be obtained from the documentation.
High amounts of energy are released in the controller. Thus, it is required to always wear
a personal protective equipment (body protection, headgear, eye protection, ear
protection, hand guard).
2
All operations concerning transport, installation, and commissioning as well as servicing
must be carried out by qualified, skilled personnel only (IEC 364 and CENELEC HD 384 or
DIN VDE 0100 and IEC−Report 664 or DIN VDE 0110. National regulations for the
prevention of accidents must be observed.).
According to this basic safety information, skilled personnel are persons who are familiar
with the installation, mounting, commissioning, and operation of the product and who
have the necessary qualifications for their occupation.
Application as directed
Drive controllers are components designed for the installation in electrical systems or
machinery. They must not be used as household appliances. They are intended exclusively
professional and commercial purposes according to EN 61000−3−2.
When installing the controllers into machines, commissioning (i.e. starting of operation as
directed) is prohibited until it is certain that the machine complies with the regulations of
EC Directive 98/37/EC (Machinery Directive). EN 60204 must be observed.
Commissioning (i.e. starting of operation as directed) is only allowed when there is
compliance with EMC Directive (89/336/EEC).
The controllers meet the requirements of the Low-Voltage Directive 2006/95/EC.
The technical data and information on the connection conditions can be obtained from the
nameplate and the documentation. They must be followed in any case.
Warning: Drive controllers are products with restricted availability according to
EN 61800−3. These products can cause radio interferences in residential areas. In this case,
special measures are required.
Transport, storage
Please observe the notes on transport, storage and appropriate handling.
Observe the climatic conditions according to the technical data.

Safety instructions
General safety and application notes for Lenze controllers
Installation
The controllers must be installed and cooled according to the instructions given in the
corresponding documentation.
Ensure proper handling and avoid mechanical stress. Do not bend any component and do
not change any insulation distance during transport or handling. Do not touch any
electronic component or contact.
Controllers contain electrostatically sensitive components which can easily be damaged
by inappropriate handling. Do not damage or destroy any electrical component since doing
so might endanger your health!
Electrical connection
When working on live controllers, the valid regulations for the prevention of accidents (e.g.
VBG 4) must be observed.
The electrical installation must be carried out according to the appropriate regulations
(e.g. cable cross/sections, fuses, PE connection). Additional information can be obtained
from the documentation.
The documentation contains information concerning installation in compliance with EMC
(shielding, earthing, filter arrangement, and cable installation). These notes must also be
observed for CE−marked controllers. The manufacturer of the system or machine is
responsible for ensuring compliance with the limit values demanded by the EMC
legislation. The controllers must be installed in housings (e.g. control cabinets) to comply
with the limit values for radio interferences valid at the site of installation. The housings
must enable an EMC−compliant installation. Make sure in particular that e.g. the control
cabinet doors have a circumferential metal connection to the housing. Reduce housing
openings and cutouts to a minimum.
Operation
If necessary, systems including controllers must be equipped with additional monitoring
and protection devices according to the valid safety regulations (e.g. law on technical
equipment, regulations for the prevention of accidents). You are allowed to adapt the
controllers to your application. Please observe the corresponding information given in the
documentation.
After the controller has been disconnected from the voltage supply, all live components
and power connections must not be touched immediately because capacitors can still be
charged.
All protection covers and doors must be kept shut during operation.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed conditions of operation
are observed.
If the ambient air is polluted, the cooling surfaces of the controller may contaminate, or the
air vents of the controller may be blocked. Therefore, the cooling surfaces and air vents
must be cleaned periodically under these operating conditions. Do not use sharp or
pointed tools for this purpose!
Waste disposal
Recycle metal and plastic materials. Assembled PCBs must be disposed of professionally.
The product−specific safety and application notes given in these instructions must be
observed!

Residual hazards
2
2.2 Residual hazards
Protection of persons
After power−off, the power terminals UL, BR and GND still carry hazardous voltages for at
least 3 minutes!
ƒ Before working on the controller, check that no voltage is applied to the power
terminals.
ƒ Always protect the power terminals against contact.
The discharge current to ground (PE) is > 3.5 mA, according to EN 50178.
ƒ If a fixed installation is required, design the PE conductor with a cable cross−section
of at least 1.5 mm
Make sure that cables are installed correctly, and that bolted connections and plug
connections are faultless.
Due to the high currents with regard to low−voltage applications, current−carrying parts
can be strongly heated.
Device protection
ƒ Connect or disconnect all pluggable terminals in a deenergised state only!
2
or use a design with double PE conductor.
ƒ A cyclic connection and disconnection of the supply voltage can overload and
destroy the input current limitation of the drive controller:
– When effecting a cyclic switching of the supply voltage over a longer period, the
period between two switch−on processes at least has to be one minute!
Motor protection
Drive systems can reach dangerous overspeeds (e.g. setting of high field frequencies for
motors and machines which are not qualified for this purpose):
ƒ The controllers do not offer any protection against these operating conditions. Use
additional components for this.
Protection of the machine/system
A missing or incorrect resolver adjustment can bring about undefined control states. The
perfect operation is no longer guaranteed.
