1 Preface and general information

1.1 The 8200 motec frequency inverter

Decentralised drive solutions require a flexible combination of motor/geared motor and frequency inverter.
The concept of the 8200 motec frequency inverter is therefore based on a modular system of matching components. Together with a Lenze geared motor or a Lenze three−phase AC motor the 8200 motec is a highly functional electronic variable speed drive.
As compact drives they can be used for adjusting speeds in different application, such as material handling, HVAC technology, automation, etc. A free combination of input and output signals and parallel operation of two interfaces ensure an individual solution for your drive task.
The 8200 motec frequency inverter is directly mounted onto the motor. Wall mounting of the 8200 motec is also possible.

1.2 About these Operating Instructions ...

These Operating Instructions are intended for all persons who install, set−up and adjust the
8200 motec frequency inverter.
A chapter informs entirely about a subject:
– You therefore only have to read the chapters you are interested in at the moment. – The Index helps you to find all information about a certain topic.
These Instructions are meant as addition to the Mounting Instructions which are part of the
delivery package: – The features and funtions are described in detail. – Examples describe how to set the parameters for typical applications. – In case of doubt, the Mounting Instructions delivered together with the 8200 motec
frequency inverter apply.
The Mounting Instructions do not inform about the use together with Lenze geared motors
and Lenze motors. The most important data are listed on the nameplates. If necessary, Operating Instructions can always be ordered from Lenze.

Lenze controllers

2 Safety information

2.1 General safety and application instructions for Lenze controllers

(According to: Low−Voltage Directive 73/23/EEC)
General
Depending on their degree of protection, some parts of Lenze controllers (frequency inverters, servo
inverters, DC controllers) and their accessory components can be live, moving and rotating during
operation. Surfaces can be hot.
Non−authorised removal of the required cover, inappropriate use, incorrect installation or operation,
creates the risk of severe injury to persons or damage to material assets.
For more information please see the documentation.
All operations concerning transport, installation, and commissioning as well as maintenance must be
carried out by qualified, skilled personnel (IEC 364 and CENELEC HD 384 or DIN VDE 0100 and IEC
report 664 or DIN VDE 0110 and national regulations for the prevention of accidents must be observed).
According to this basic safety information, qualified, skilled personnel are persons who are familiar with
the assembly, installation, commissioning, and operation of the product and who have the qualifications
necessary for their occupation.
Application as directed
Drive controllers are components which are designed for installation in electrical systems or machinery.
They are not to be used as domestic appliances, but only for industrial purposes according to
EN 61000−3−2.
When installing drive controllers into machines, commissioning of these controllers (i.e. the starting of
operation as directed) is prohibited until it is proven that the machine corresponds to the regulations of
the 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 the
EMC Directive (89/336/EEC).
The controllers meet the requirements of the Low−Voltage Directive 73/23/EEC. The harmonised
standard EN 61800−5−1 applies to the controllers.
The technical data as well as the connection conditions can be obtained from the nameplate and the
documentation. They must be strictly observed.
Warning: The controllers are products which can be installed in drive systems of category C2 according
to EN 61800−3. These products can cause radio interference 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.
Ensure proper handling and avoid 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 components, which can easily be damaged by
inappropriate handling. Do not damage or destroy any electrical components since this might endanger
your health!

Safety instructions
Lenze controllers
Electrical connection
When working on live controllers, the valid national regulations for the prevention of accidents (e.g. VBG 4) must be observed.
Carry out the electrical installation in compliance with the corresponding regulations (e.g. cable cross−sections, fuses, PE connection). More detailed information is given in the corresponding documentation.
Notes about installation according to EMC regulations (shielding, earthing, filters and cable routing) are included in the documentation. These notes also apply to CE−marked controllers. The compliance with limit values required by the EMC legislation is the responsibility of the manufacturer of the machine or system. 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 should have a circumferential metal connection to the housing. Reduce housing openings and cutouts to a minimum.
Lenze controllers can cause a DC current in the protective conductor. If a residual current device (RCD) is used as a protective means in the case of direct or indirect contact, only a residual current device (RCD) of type B may be used on the current supply side of the controller. Otherwise, another protective measure, such as separation from the environment through double or reinforced insulation or disconnection from the mains by means of a transformer must be used.
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 controller can be adapted to your application. Please observe the corresponding information given in the documentation.
After a 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. Please observe the corresponding stickers on the controller.
All protection covers and doors must be shut during operation. Note 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 Annex 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 conditions of operation are observed. If the ambient air is polluted, the cooling surfaces of the controller may become dirty or the air vents of
the controller may be obstructed. Therefore, clean the cooling surfaces and air vents periodically under these operating conditions. Do not use sharp or pointed tools for this purpose!
Waste 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!

5 Commissioning

5.1 Before you start

Tip!
The controller is factory−set to drive the following four−pole standard asynchronous motors:
– 230/400 V, 50 Hz – 280/480 V, 60 Hz – 400 V, 50 Hz
Maintain the switch−on sequence. ( 5−6)In the event of an error during commissioning please see the "Troubleshooting and fault
elimination" chapter: ( 8−1)
Commissioning
Before you start
Check ...
... before the mains voltage is connected
the wiring for completeness, short circuit, and earth faultIf no function module is used (delivery status):
– Has the FIF cover been mounted?
If the internal voltage source X3/20 of the standard I/O is used:
– Are the terminals X3/7 and X3/39 bridged?
... the most important drive parameters settings before the controller is enabled
Has the V/f rated frequency been adapted to the motor circuit configuration? ( 7−5)Have the configuration of the analog inputs and outputs been adapted to the wiring? ( 7−57)Have the configuration of the digital inputs and outputs been adapted to the wiring? ( 7−68)Are the drive parameters relevant for your application set correctly?
If required, use the keypad or PC to adapt them. ( 6−1 ff)

5.2 Before switching on

( STOP!
Special commissioning procedure after long−time storage
If controllers have been stored for more than 2 years, their DC−bus capacitors may have dried out.
Possible consequences:
l The DC−bus capacitors and thus the controller will be damaged at the first
switch−on.
Protective measures:
l Anodize the DC−bus capacitors before commissioning. A detailed set of
instructions can be downloaded from the Internet (www.Lenze.com).

Tip!
Signal flow charts show how codes are integrated into signal processing. ( 14−1 ff.) The code table lists all codes in numerical order and explains them briefly. ( 14−10 ff.)
For free signal configuration:
Select the source from the targets point of view:
– Ask yourself Where does the signal come from?" – That makes it easy to find the correct entry for a code.
A source can have several targets:
– It is thus possible that double assignments occur when targets are assigned to sources. – For instance, the assignment of E1 remains the same even if the frequency input E1 is
activated (Lenze setting: "JOG1 activation!). The previous assignment must be deleted with C0410/1 = 255 to ensure trouble−free operation.
– Ensure that only the targets wanted are assigned to a source.
A target can have one source only.

V/f characteristic controlVector controlSensorless torque control
Selection of the correct operating mode
V/f characteristic control is the classic operating mode for standard applications.
The vector control provides a better control performance than the V/f characteristic control due to:
a higher torque over the whole speed rangea higher speed accuracy and concentricity factora higher efficiency

7.1.1 V/f characteristic control
Description
The output voltage of the controller follows a defined characteristic. At low output frequencies, the characteristic can be boosted. It can be adapted to different load profiles.
Linear characteristic for drives with constant load torque over the speed.Quadratic characteristic for drives with quadratic load torque over the speed:
– Quadratic V/f characteristics are preferably used in centrifugal pump and fan drives.
However, it must be checked whether your pump or fan drive can be operated in this operating mode!
– If your pump or fan drive cannot be used for the operation with a quadratic V/f
characteristic, the linear V/f characteristic or vector control mode must be used.

Setting the V/f characteristic
Under C0014 select the V/f characteristic suitable for your application.
) Note!
The following must be observed when operating drives with square−law V/f characteristic:
l High moments of inertia reduce the acceleration of the drive. l This drive behaviour can be avoided by using the linear V/f characteristic via the
parameter set changeover during the acceleration.
Setting of V/f rated frequency 10
The V/f rated frequency determines the slope of the V/f characteristic and has considerable influence on the current, torque and power performance of the motor.
The setting under C0015 applies to all admitted mains voltages.The internal mains voltage compensation compensates deviations in the mains during
operation. Therefore, they do not have to be considered for the setting of C0015.
Depending on the settings under C0015 it can be necessary to adapt the maximum output
frequency under C0011 to ensure that the entire speed range will be used.
The V/f rated frequency depends on the rated controller voltage, the rated motor voltage, and
the rated motor frequency:

Description
Compared with the V/f characteristic control the vector control offers considerably higher torque and lower current consumption during idle running. The vector control is an improved motor current control following the Lenze FTC technology. Select vector control for operation of the following drives:
Single drives with extremely changing loadsSingle drives with heavy start conditionsSensorless speed control of standard three−phase AC motors
) Note!
l The connected motor should maximally be two power classes lower than the
motor assigned to the controller.
l The operation with vector control is not possible if several drives are operated on
one controller.
l The motor parameter identification is absolutely vital! Otherwise commissioning
is not possible.

Rough motor run and motor current (C0054) > 60 % rated motor current in idle running (stationary operation)
Torque too low for frequencies f < 5 Hz (starting torque) Increase of motor resistance (C0084) or increase of motor inductance
Poor constant speed at high loads (setpoint and motor speed are not proportional).
Error messages OC1, OC3, OC4 or OC5 during acceleration times (C0012) < 1 s (drive controller is no longer able to follow the dynamic processes)
1. Reduction of motor inductance (C0092) by 10 %
2. Check of motor current under C0054
3. If the motor current (C0054) > 50 % of the rated motor current: – C0092 must be reduced until the motor current amounts to 50 %
of the rated motor current – Reduce C0092 by max. 20 %! – Note: If you reduce C0092 the torque will decrease!

7.1.3 Sensorless torque control with speed limitation
Description
The setpoint linked with C0412/6 is interpreted as torque setpoint. Actual values are not required. The controller varies the speed within the set frequency range in dependence of the load and the torque selected.
The speed is limited via setpoint 1 or the maximum frequency.
Application with, for instance, winding drives.
) Note!
l The sensorless torque control only operates in motor mode, not in generator
mode.
l The motor parameter identification is absolutely vital! Otherwise commissioning
is not possible.

Optimising the sensorless torque control

The minimum torque setpoint must not fall below 10 % (setting range 1 : 10).The motor may stall at operation with output frequencies < 3 Hz. If so, reset the internal
control by quickly switching the controller inhibit.
If C0412/6 is combined with an analog signal source it is possible to display the torque
setpoint under C0047.
If C0412/6 is not combined with an analog signal source (FIXED−FREE) it is possible to select
the torque setpoint under C0047. Please note: – When disconnecting the mains, the value set will be lost! – Before enabling the controller it is absolutely necessary at the restart to select the correct
setpoint under C0047. Otherwise the drive would start with the maximum torque.

7.4 Limit value setting

7.4.1 Speed range
Description
The speed setting range required for the application can be set via the selection of output frequencies:
The minimum output frequency (C0010) corresponds to the speed at 0 % speed setpoint
selection.
The maximum output frequency (C0011) corresponds to the speed at 100 % speed setpoint
selection.
The lower frequency limitation (C0239) sets the speed. Independently of the setpoint, the
value cannot fall below this speed (e.g. for fans, dancer position control, or dry running protection for pumps).

"Minimum output frequency" characteristics:

– on the analog input 2 of the application I/O. – when the setpoint is selected via frequency input.
C0010 C0011:
– C0011 is approached via the acceleration ramp regardless of the selected analog setpoint. – The output frequency is limited to C0011. – The analog input gain must be set to zero (C0027 = 0), to ensure a trouble−free operation.
C0011
"Maximum output frequency" characteristics:
When selecting fixed setpoint (JOG) C0011 acts as limitation.C0011 is an internal normalisation variable! Bigger changes should only be made when the
controller is inhibited!
( Stop!
Set C0011 so that the maximum permissible motor speed will not be exceeded. Otherwise the motor can be destroyed.
C0239
"Lower frequency limitation" characteristics:
When using standard I/O, C0239 is approached without acceleration ramp (jolt!). When using
application I/O, C0236 can be used to set an acceleration time for C0239.
C0239 = 0.00 Hz only allows one direction of rotation.
Tip
For output frequencies > 300Hz, switching frequencies < 8kHz must be avoided.The display values of C0010 and C0011 can be related to a process variable under C0500
and C0501.

7.4.2 Current limits
Description
The controllers are equipped with a current−limit control which determines the dynamic response under load. The measured load is compared with the limit values set under C0022 for motor load and C0023 for generator load. If the current limit is exceeded, the controller will change its dynamic behaviour:
Controller performance when a limit value is reached
Motor overload during acceleration:
The controller prolongs the acceleration ramp.
Generator overload during deceleration:
The controller prolongs the deceleration ramp.
With increasing load and constant speed:
When the current limit of the motor mode is reached:
– The controller reduces the output frequency to 0Hz. – The controller cancels the change of the output frequency if the load falls below the limit
value.
When the current limit in the generator mode is reached:
– The controller increases the output frequency up to the maximum frequency (C0011). – The controller cancels the change of the output frequency if the load falls below the limit
value.
If suddenly a load is applied to the motor shaft (e.g. drive is blocked), the overcurrent
switch−off can be activated (error message OCX).

C0022 and C0023 refer to the rated output current at a switching frequency of 8 kHz.When operating with a switching frequency of 16 kHz you must adapt C0022 and C0023 to
the permissible output currents (derating).
Correct current control for operation in generator mode is only possible with external brake
resistor.
C0023 = 30 %
At V/f characteristic control the current−limit controller is not active for the operation in generator mode with C0023 = 30%:
Possibly reasonable in applications with medium frequency asynchronous motors if motor
and generator mode cannot be detected as fault−free.
Drive behaviour in case of motor and generator overload (C0054 > C0022):
– The controller reduces the output frequency to 0Hz. – The controller cancels the change of the output frequency if the load falls below the limit
value.
