Safety instructions
General safety and application notes for Lenze controllers
Application as directed
Controllers are components which are designed for installation in electrical systems or
machines. They are not to be used as domestic appliances, but only for industrial purposes
according to EN 61000−3−2.
When controllers are installed into machines, commissioning (i.e. starting of the operation
as directed) is prohibited until it is proven that the machine complies with the regulations
of the EC Directive 98/37/EC (Machinery Directive); EN 60204 must be observed.
Commissioning (i.e. starting of the operation as directed) is only allowed when there is
compliance with the EMC Directive (2004/108/EC).
The controllers meet the requirements of the Low−Voltage Directive 2006/95/EC. The
harmonised standard EN 61800−5−1 applies to the controllers.
The technical data and supply conditions can be obtained from the nameplate and the
documentation. They must be strictly observed.
Warning: Controllers are products which can be installed in drive systems of category C2
according to EN 61800−3. These products can cause radio interferences in residential areas.
In this case, special measures can be necessary.
Transport, storage
Please observe the notes on transport, storage, and appropriate handling.
Observe the climatic conditions according to the technical data.
Installation
The controllers must be installed and cooled according to the instructions given in the
corresponding documentation.
The ambient air must not exceed degree of pollution 2 according to EN 61800−5−1.
Ensure proper handling and avoid excessive mechanical stress. Do not bend any
components and do not change any insulation distances during transport or handling. Do
not touch any electronic components and contacts.
Controllers contain electrostatically sensitive devices which can easily be damaged by
inappropriate handling. Do not damage or destroy any electrical components since this
might endanger your health!

EDKVF93−04 EN 2.0
Safety instructions
General safety and application notes for Lenze controllers
Electrical connection
When working on live controllers, observe the applicable national regulations for the
prevention of accidents (e.g. VBG 4).
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 on the installation according to EMC (shielding,
earthing, arrangement of filters, and installation of the cables). Also observe this
information with regard to drive controllers labelled with CE marking. The manufacturer
of the system or machine is responsible for the compliance of the limit values required in
connection with EMC legislation. In order to observe the limit values for radio interference
emissions effective at the installation site, you have to mount the drive controllers into
housings (e. g. control cabinets). The housings have to enable an EMC−compliant structure.
Particularly observe that, for instance, control cabinet doors preferably are metallically
connected to the housing in a circumferential manner. Reduce openings or apertures
through the housing to a minimum.
Lenze controllers can cause a DC current in the PE conductor. If a residual current device
(RCD) is used for the protection in the case of direct or indirect contact on a three−phase
supplied controller, only one residual current device of type B is permissible on the current
supply side of the controller. If the controller is supplied with one phase, also a residual
current device (RCD) of type A may be used. Apart from the use of a residual current device
(RCD) also other protective measures can be used, like for instance isolation from the
environment by double or reinforced insulation or isolation from the supply system by a
transformer.
2
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). The controllers can be adapted to
your application. Please observe the corresponding information given in the
documentation.
After the controller has been disconnected from the supply voltage, all live components
and power connections must not be touched immediately because capacitors can still be
charged. Please observe the corresponding stickers on the controller.
All protection covers and doors must be shut during operation.
Notes for UL−approved systems with integrated controllers: UL warnings are notes that
only apply to UL systems. The documentation contains special UL notes.
Safety functions
Special controller variants support safety functions (e.g. "safe torque off", formerly "safe
standstill") according to the requirements of appendix I No. 1.2.7 of the EC Directive
"Machinery" 98/37/EC, EN 954−1 category 3 and EN 1037. Strictly observe the notes on the
safety functions given in the documentation on the respective variants.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed operating conditions are
observed.

Residual hazards
2
2.2 Residual hazards
Protection of persons
ƒ Before working on the controller, check that no voltage is applied to the power
terminals:
– The power terminals U, V, W, +U
least five minutes after disconnecting from the mains.
– The power terminals L1, L2, L3, U, V, W, +U
live when the motor is stopped.
ƒ The leakage current to earth (PE) is >3.5 mA. EN 50178 requires a fixed installation.
ƒ The heatsink of the controller has an operating temperature of > 80 °C:
– Direct skin contact causes burns.
ƒ During the parameter set transfer, the control terminals of the controller can
assume undefined states.
– For this reason, the connectors X5 and X6 have to be unplugged before the
transfer is executed. This ensures that the controller is inhibited and all control
terminals are in the defined state LOW".
Device protection
, −UG, BR1, BR2 and 101 ... 104 remain live for at
G
, −UG, BR1, BR2 and 101 ... 104 remain
G
ƒ Frequent mains switching (e.g. inching mode via mains contactor) can overload and
destroy the input current limitation of the controller.
– Thus, at least five minutes have to pass between two switch−on processes.
– In case of frequent, safety−related disconnections use the "safe torque off" safety
function (STO).
Motor protection
ƒ Certain drive controller settings can overheat the connected motor:
– E. g. long−time operation of the DC injection brake.
– Long−time operation of self−ventilated motors at low speeds.
Protection of the machine/system
ƒ Drives can reach dangerous overspeeds (e. g. setting of high output frequencies in
connection with motors and machines not suitable for this purpose):
– The drive controllers do not provide protection against such operating conditions.
For this purpose, use additional components.

3.1.5 Loading a parameter set
The keypad serves to load a saved parameter set into the main memory when the controller
is inhibited. After the controller is enabled, it operates with the new parameters.
Danger!
ƒ When a new parameter set is loaded, the controller is reinitialised and acts
as if it had been connected to the mains:
– System configurations and terminal assignments can be changed. Make
sure that your wiring and drive configuration comply with the settings of
the parameter set.
ƒ Only use terminal X5/28 as source for the controller inhibit! Otherwise the
drive may start in an uncontrolled way when switching over to another
parameter set.
Note!
ƒ After switching on the supply voltage, the controller always loads parameter
set 1 into the main memory.
ƒ It is also possible to load other parameter sets into the main memory via the
digital inputs or bus commands.

3.1.6 Transferring parameters to other standard devices
Parameter settings can be easily copied from one standard device to another by using the
keypad.
For this purpose use the "Load/Store" menu
Danger!
During the parameter transfer from the keypad to the standard device the
control terminals can adopt undefined states!
Therefore the plugs X5 and X6 must be disconnected from the standard device
before the transfer takes place. This ensures that the controller is inhibited and
all control terminals have the defined state "LOW".
Copying parameter sets from the standard device into the keypad
Note!
After copying the parameter sets into the XT keypad (C0003 = 11), always the
parameter set that was loaded last via C0002 is activated.
Like this the current parameters also remain active after copying:

although C0597 = 0 or 2
If during high speeds
DC−injection braking (GSB)
is activated, the fault OC1

The motor phases are reversed so that the rotating field
of the motor is not identical with the rotating field of
the feedback system. The drive shows the following
behaviour:

l Vector control (C0006 = 1)
– The motor rotates slowly with maximum slip speed
(depending on motor data and maximum current)
and does not react to a speed setpoint. The
direction of rotation, however, is determined by
the sign of the speed setpoint.
– The motor current rises up to I

delay.
The two terminal strips X5 are reversed. Since X5/A1 and
X5/28 face each other, the controller can be enabled if
the control terminals are internally supplied. All other
connections, however, are assigned incorrectly so that
the motor cannot start.
The function block MLP1 is not entered into the
processing table.
During DC−injection braking the controller sets pulse
inhibit for a short time (DCTRL−IMP) to reduce the
magnetisation in the motor before a DC voltage is
injected into the motor. At high speeds (e. g. in case of
mid−frequency motors) the residual voltage which
develops from the residual magnetism and high speed
can generate such a high motor current that OC1 or OU
are activated.

Controller in clamp operation
The clamp operation is a permissible operating mode. But since, however, pulse inhibit is
set again and again, the controller cannot provide the optimum power.
If the output power is optimal, the output current mainly is right below the clamp

If the DC−bus voltage (UDC) exceeds the switch−off threshold OU, pulse inhibit will be set.
At the same time, an internal timer for a delay time (C0912) will be started.
Pulse inhibit will be reset, if the voltage falls below the switch−on threshold OU and the
delay time has elapsed.
