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!

EDKVF93−01 EN 3.0
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.
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.
EDKVF93−01 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
2.2 Thermal 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.
2
x t monitoring has been designed such that it will be activated after 179 s in the
The I
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.
Behaviour of the I2 x t monitoring Condition
The I2 x t monitoring is deactivated.
C0066 is set = 0 % and
MCTRL−LOAD−I2XT is set = 0.00 %.
I2 x t monitoring is stopped.
The current value in C0066 and at the
MCTRL−LOAD−I2XT output is frozen.
I2 x t monitoring is deactivated.
The motor load is displayed in C0066.
When C0120 = 0 % and C0127 = 0 %, set controller
inhibit.
When C0120 = 0 % and C0127 = 0 %, set controller
enable.
Set C0606 = 3 (off) and C0127 > 0 %.

Note!
An error message OC6 or OC8 can only be reset if the I2 x t load falls below the
set trigger threshold by 5 %.

Due to the construction, self−ventilated standard motors are exposed to an increased heat
generation in the lower speed range compared to forced ventilated motors.

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:
ƒ Point : Definition with C0129/1
This value also enables an increase of the maximally permissible load.
ƒ Point : Definition with C0129/2
With increasing speeds, the maximally permissible load remains unchanged
(I

In Fig. 2−2, the motor speed and the corresponding permissible motor torque () can be
read for each working point (on the characteristic () ... ). can also be calculated
using the values in C0129/1and C0129/2 (evaluation coefficient "y", 15).
