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 2006/42/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 electrostatic sensitive devices which can easily be damaged by
inappropriate handling. Do not damage or destroy any electrical components since this
might endanger your health!

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.
This documentation contains information on installation in compliance with EMC
(shielding, earthing, filter, and cables). These notes must also be observed for CE−marked
controllers. The manufacturer of the system is responsible for compliance with the limit
values demanded by EMC legislation. The controllers must be installed in housings (e.g.
control cabinets) to meet the limit values for radio interferences valid at the site of
installation. The housings must enable an EMC−compliant installation. Observe 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.
Lenze controllers may cause a DC current in the PE conductor. If a residual current device
(RCD) is used for protection against direct or indirect contact for a controller with
three−phase supply, only a residual current device (RCD) of type B is permissible on the
supply side of the controller. If the controller has a single−phase supply, a residual current
device (RCD) of type A is also permissible. Apart from using a residual current device (RCD),
other protective measures can be taken as well, e.g. electrical isolation by double or
reinforced insulation or isolation from the supply system by means of 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 terminals 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.
Safety functions
Certain controller versions support safety functions (e.g. "Safe torque off", formerly "Safe
standstill") according to the requirements of the EC Directive 2006/42/EC (Machinery
Directive). The notes on the integrated safety system provided in this documentation must
be observed.
Maintenance and servicing
The controllers do not require any maintenance if the prescribed operating conditions are
observed.
EDKVF93−02 EN 3.0
Disposal
Recycle metal and plastic materials. Ensure professional disposal of assembled PCBs.
The product−specific safety and application notes given in these instructions must be
observed!

Thermal motor monitoring
2.2Thermal motor monitoring
Note!
From software version 8.1 onwards, the 9300 vector controllers are provided
with an I2xt function for sensorless thermal monitoring of the connected
motor.
2
ƒ I
xt monitoring is based on a mathematical model which calculates a
thermal motor utilisation from the detected motor currents.
ƒ The calculated motor utilisation is saved when the mains is switched off.
ƒ The function is UL−certified, i.e. additional protective measures for the motor
are not required in UL−approved systems.
ƒ Nevertheless, I
because other influences on the motor utilisation such as changes in the
cooling conditions (e.g. cooling air flow interrupted or too warm) cannot be
detected.
2
xt monitoring does not provide full motor protection
2
x t load of the motor is displayed in C0066.
Die I
The thermal loading capacity of the motor is expressed by the thermal motor time
constant (t, C0128). Find the value in the rated motor data or contact the manufacturer of
the motor.

event of a motor with a thermal motor time constant of 5 minutes (Lenze setting C0128),
a motor current of 1.5 x I
and a trigger threshold of 100 %.
N
Two adjustable trigger thresholds provide for different responses.
ƒ Adjustable response OC8 (TRIP, warning, off).
– The trigger threshold is set in C0127.
– The response is set in C0606.
– The response OC8, for instance, can be used for an advance warning.
ƒ Fixed response OC6−TRIP.
– The trigger threshold is set in C0120.

The lowered speed / torque characteristic (Fig. 2−2) reduces the permissible thermal load
of self−ventilated standard motors. The characteristic is a line the definition of which
requires two points:

– Because the power terminals L1, L2, L3; U, V, W, +U
motor is stopped.
ƒ The leakage current to earth (PE) is >3.5 mA. According to EN 61800−5−1
– a fixed installation is required,
– a double PE connection is required, or, if there is only a single PE connection, the PE
conductor must have a cross−section of at least 10 mm
ƒ The heat sink of the controller has an operating temperature of > 80 °C:
– Contact with the heatsink results in burns.

ƒ If you use the "flying−restart circuit" function (C0142 = 2, 3) for machines with a low
moment of inertia and minimum friction:
– After controller enable in standstill, the motor may start or change its direction of
rotation for a short time, because the flying restart process also is carried out at a
speed of 0.
ƒ During parameter set transfer, the control terminals of the controller can have
undefined states!
– Therefore the plugs X5 and X6 must be unplugged, before the transfer is executed.
This ensures that the controller is inhibited and all control terminals have the
defined "LOW" state.
Device protection
ƒ Frequent mains switching (e.g. inching mode via mains contactor) can overload and
destroy the input current limitation of the drive controller:
– At least 3 minutes must pass between switching off and restarting the devices
EVS9321−xS and EVS9322−xS.
– At least 3 minutes must pass between two starting procedures of the devices
EVS9323−xS ... EVS9332−xS.
– Use the "safe torque off" safety function (STO) if safety−related mains
disconnections occur frequently. The drive variants Vxx4 are equipped with this
function.
16
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.

3.1.5Loading 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.

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:

4.5.2Resetting system error messages
ResponseMeasures for resetting the fault message
TRIP
Message
WarningAfter elimination of the fault, the fault message is cancelled automatically.
Note!
If a TRIP source is still active, the pending TRIP cannot be reset.
Resetting the TRIP can be effected by:
l Pressing the keypad XT EMZ9371 BC ð %. Then press $ to re−enable the controller.
l Setting code C0043 = 0.
l Control word C0135, bit 11
l Control word AIF
l Control word of system bus (CAN)
After resetting the TRIP, the drive remains at standstill.
Danger!
After elimination of the fault, the fault message is cancelled automatically and the drive restarts
automatically.
