Danger!
Disregarding the following basic safety measures may lead to
severe personal injury and damage to material assets!
ƒ Lenze drive and automation components ...
... must only be used for the intended purpose.
... must never be operated if damaged.
... must never be subjected to technical modifications.
... must never be operated unless completely assembled.
... must never be operated without the covers/guards.
... can − depending on their degree of protection − have live, movable or
rotating parts during or after operation. Surfaces can be hot.
Transport, storage
ƒ All specifications of the corresponding enclosed documentation must
be observed.
This is vital for a safe and trouble−free operation and for achieving the
specified product features.
The procedural notes and circuit details provided in this document are
proposals which the user must check for suitability for his application.
The manufacturer does not accept any liability for the suitability of the
specified procedures and circuit proposals.

Mechanical installation
Electrical installation
ƒ Install the product according to the regulations of the corresponding
documentation. In particular observe the section "Operating
conditions" in the chapter "Technical data".
ƒ Provide for a careful handling and avoid mechanical overload. During
handling neither bend components, nor change the insulation
distances.
ƒ The product contains electrostatic sensitive devices which can easily be
damaged by short circuit or static discharge (ESD). Thus, electronic
components and contacts must not be touched unless ESD measures
are taken beforehand.
ƒ Carry out the electrical installation according to the relevant
regulations (e. g. cable cross−sections, fusing, connection to the PE
conductor). Additional notes are included in the documentation.
ƒ When working on live products, observe the applicable national
regulations for the prevention of accidents (e.g. BGV 3).
ƒ The documentation contains information about EMC−compliant
installation (shielding, earthing, arrangement of filters and laying
cables). The system or machine manufacturer is responsible for
compliance with the limit values required by EMC legislation.
Warning: The controllers are products which can be used in category C2
drive systems as per EN 61800−3. These products may cause radio
interference in residential areas. If this happens, the operator may need
to take appropriate action.
ƒ For compliance with the limit values for radio interference emission at
the site of installation, the components − if specified in the technical
data − have to be mounted in housings (e. g. control cabinets). The
housings have to enable an EMC−compliant installation. In particular
observe that for example control cabinet doors preferably have a
circumferential metallic connection to the housing. Reduce openings or
cutouts through the housing to a minimum.
ƒ Only plug in or remove pluggable terminals in the deenergised state!
Commissioning
Operation
Safety functions
2.1−2
ƒ If required, you have to equip the system with additional monitoring
and protective devices in accordance with the respective valid safety
regulations (e. g. law on technical equipment, regulations for the
prevention of accidents).
ƒ Before commissioning remove transport locking devices and keep them
for later transports.
ƒ Keep all protective covers and doors closed during operation.
ƒ Without a higher−level safety system, the described product must
neither be used for the protection of machines nor persons.
ƒ Certain controller versions support safety functions (e.g. "Safe torque
off", formerly "Safe standstill").
The notes on the safety functions provided in the documentation of the
versions must be observed.

Maintenance and servicing
Disposal
ƒ The components are maintenance−free if the required operating
conditions are observed.
ƒ If the cooling air is polluted, the cooling surfaces may be contaminated
or the air vents may be blocked. Under these operating conditions, the
cooling surfaces and air vents must be cleaned at regular intervals.
Never use sharp objects for this purpose!
ƒ Only replace defective fuses in the deenergised state to the type
specified.
ƒ After the system has been disconnected from the supply voltage, live
components and power connections must not be touched immediately
because capacitors may be charged. Please observe the corresponding
notes on the device.
ƒ Recycle metals and plastic materials. Ensure professional disposal of
assembled PCBs.

x t−monitoring is designed in a way, that a motor with a thermal motor
time factor of 5 min, a motor current of 1.5 x I
and a trigger threshold of
r
100 % releases the monitoring after 179 s.
You can set different reactions with two adjustable trigger thresholds.
ƒ Adjustable reaction OC8 (TRIP, Warning, Off).
– The reaction is set in C0606.
– The trigger threshold is set in C0127.
– The reaction OC8 can be used for example for an advance warning.
ƒ Fixed reaction OC6−TRIP.
– The trigger threshold is set in C0120.
Response of the I2 x t−monitoring Condition
The I2 x t−monitoring is deactivated.
C0066 = 0 % and
MCTRL−LOAD−I2XT = 0,00 % is set.
The I2 x t−monitoring is stopped.
The actual value in C0066 and at the
MCTRL−LOAD−I2XT output is held.
The I2 x t−monitoring is deactivated.
The motor load is displayed in C0066.
Set the controller inhibit at C0120 = 0 % and
C0127 = 0 %.
Allow controller release at C0120 = 0 % and
C0127 = 0 %.
Set C0606 = 3 (Off) and C0127 > 0 %.

Note!
An OC6 or OC8 error message can only be reset if the
I2 × t−monitoring has fallen below the set trigger threshold by
5 %.

Protection of persons
ƒ According to their enclosure, Lenze controllers (frequency inverters,
servo inverters, DC speed controllers) and their components can carry a
voltage, or parts of the controllers can move or rotate during operation.
Surfaces can be hot.
– If the required cover is removed, the controllers are used
inappropriately or installed or operated incorrectly, severe damage to
persons or material assets can occur.
– For more detailed information please see the documentation.
ƒ There is a high amount of energy within the controller. Therefore
always wear personal protective equipment (body protection,
headgear, eye protection, ear protection, hand guard) when working on
the controller when it is live.
ƒ Before working on the controller, check if no voltage is applied to the
power terminals.
– the power terminals U, V, W, +U
, −UG, BR1, BR2 and 101 ... 104 still
G
carry dangerous voltage for at least 5 minutes after power−off.
– the power terminals L1, L2, L3, U, V, W, +U
, −UG, BR1, BR2 and
G
101 ... 104 carry dangerous voltage when the motor is stopped.
ƒ Before power−off during DC−bus operation, all controllers must be
inhibited and disconnected from the mains.
Device protection
ƒ The discharge current to PE potential is > 3.5 mA. In accordance with
EN 61800−5−1
– a fixed installation is required.
– the design of the PE conductor has to be double or, in the case of a
single design, must have a cable cross−section of at least 10 mm
2
.
ƒ The controller can only be safely disconnected from the mains via a
contactor on the input side.
ƒ During parameter set transfer the control terminals of the controller
can have undefined states.
– Therefore the connectors X5 and X6 must be disconnected from the
controller before the transfer takes place. This ensures that the
controller is inhibited and all control terminals have the defined state
"LOW".
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 For some controller settings, the connected motor may overheat (e.g.
when operating the DC injection brake or a self−ventilated motor at
low speed for longer periods).
– Using an overcurrent relay or a temperature monitoring device
provides a large degree of protection against overload.
– We recommend to use PTC thermistors or thermal contacts for motor
temperature monitoring. (Lenze three−phase AC motors are equipped
with thermal contacts (NC contacts) as standard)
– PTC thermistors or thermal contacts can be connected to the
controller.
ƒ Drives can attain dangerous overspeeds (e.g. setting of high output
frequencies with motors and machines not qualified for this purpose).
