1.1
General safety and application notes for Lenze controllers
(according to Low-Voltage Directive 73/23/EEC)
1. General
Lenze controllers (frequency inverters, servo inverters, DC controllers) can carry a voltage or parts of the controllers can 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 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.
2. Intended use
Drive controllers are components which are designed for the installation into electrical systems or machinery. They are not to be used as domestic appliances, but only for industrial purposes according to EN 61000-3-2. The documentation contains information about the compliance of the limit values with EN 61000-3-2.
When installing controllers into machines, commissioning of the drive 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/EG (Machinery Directive); EN 60204 (VDE 0113) 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 drive controllers meet the requirements of the Low-Voltage Directive 73/23/EEC. The harmonised standards EN 50178/DIN VDE 0160 apply to the controllers.
The technical data as well as the connection conditions can be obtained from the nameplate and the documentation. The instructions given must be strictly observed.
Warning: Controllers are products with restricted availability according to EN 61800-3. These products can cause interferences in residential premises. If controllers are used in residential premises, corresponding measures are required.
3. Transport, storage
The notes on transport, storage and appropriate handling must be observed.
Climatic conditions according to EN 50178 apply.
4. Installation
The controllers must be installed and cooled according to the regulations given in the corresponding Instructions.
Ensure careful handling and avoid mechanical overload. Do not bend any components and do not change the insulation distances during transport and storage. Electronic components and contacts must not be touched.
Controllers contain electrostatically sensitive components which can easily be damaged by inappropriate handling. Do not damage or destroy any electrical components since this could mean hazards for your health!
5. Electrical connection
When working on live controllers, the valid national regulations for the prevention of accidents (e. g. VBG 4) must be observed.
The electrical installation must be carried out in compliance with the corresponding regulations (e.g. cable cross-sections, fuses, PE connection). Additional notes and information can be obtained from the corresponding Instructions.
The Instructions contain notes concerning wiring according to EMC regulations (shielding, earthing, filters and cable routing). These notes must also be observed when using CE-marked controllers. The compliance with limit values required by the EMC legislation is the responsibility of the manufacturer of the machine or system.
6. Operation
If necessary, systems including controllers must be equipped with additional monitoring and protection devices according to the applying safety regulations (e.g. regulation for technical equipment, regulation for the prevention of accidents). The controller can be adapted to your application. Please observe the corresponding information given in the Instructions.
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 which only apply to UL systems. The Instructions give UL-related information.
7. Safe standstill
The variant V004 of 9300 and 9300 vector, the variant Bx4x of 8200 vector controller and the axis controller ECSXA064 support the function ”Safe standstill”, protection against unexpected start, according to the requirements of Annex I No. 1.2.7 of the EC Directive ”Machinery” 98/37/EG, DIN EN 954-1 category 3 and DIN EN 1037. Please observe the notes on the function ”Safe standstill” given in the corresponding Instructions.

Lenze low-voltage machinery
1.2
General safety and application notes for Lenze low-voltage machinery
(in conformity with the Low-Voltage Directive 73/23/EEC)
1. General
Low-voltage machines have dangerous, live and rotating parts as well as possibly hot surfaces. All operations serving transport, connection, commissioning and maintenance are to be carried out by skilled, responsible technical personnel (observe EN 50110-1 (VDE 0105-100); IEC 60364). Improper handling can cause severe injuries or damages.
Synchronous machines induce voltages at open terminals during operation.
2. Application as directed
These low-voltage machines are intended for industrial and commercial installations. They comply with the harmonized standards of the series EN 60034 (VDE O53O).
Their use in hazardous areas is prohibited unless they are expressly intended for such use (follow additional instructions).
The enclosures ≤ IP23 are by no means intended for outdoor use. Air-cooled designs are rated for ambient temperatures between -15 °C and -10 °C and +40 °C and altitudes
≤ 1000 m a.m.s.l., from -20 °C to +40 °C without brake or with spring-operated brake, with separate ventilation or self ventilation, from -15 °C to +40 °C with permanent magnet brake and from -10 °C to +40 °C with separate fan. Check indications on the nameplate and if they are different, observe them. The conditions on site must correspond to all nameplate data.
Low-voltage machines are components for the installation into machines as defined in the Machinery Directive 98/37/EC. Commissioning is prohibited until the conformity of the end product with this Directive has been established (follow a.o. EN 60204-1).
The integrated brakes cannot be used as safety brakes. It cannot be ruled out that factors which cannot be influenced, such as oil ingression because of a defective A-side shaft seal, cause a torque reduction.
3. Transport, storage
The forwarder must be informed directly after receipt of the goods about all damages or deficiencies; if necessary, commissioning must be stopped. Tighten screwed-in ring bolts before transport. They are designed for the weight of the low-voltage machine, do not apply extra loads. If necessary, use suitable and adequately dimensioned means of transport (e.g. rope guides).
Remove the shipping brace before commissioning. Reuse it for further transports. For storage of low-voltage machines ensure a dry, dust-free and low-vibration
(v rms
≤ 0.2 mm/s) environment (danger of bearing damage at rest). Measure the insulation resistance before commissioning. If the values are ≤ 1 kΩ per volt of rated voltage, dry the winding.
4. Installation
Ensure an even surface, solid foot or flange mounting and exact alignment if a direct clutch is connected. Avoid resonances with the rotational frequency and double mains frequency which may be caused by the assembly. Turn rotor by hand, listen for unusual slipping noises. Check the direction of rotation when the clutch is not active (observe section 5).
Use appropriate tools to mount or remove belt pulleys and clutches (heat generation!) and cover them with a touch guard. Impermissible belt tensions must be avoided
(technical list).
The machines are half-key balanced. The clutch must be half-key balanced, too. The visibly protruding part of the key must be removed.
If required, provide pipe connections. Mounting positions with shaft end at bottom must be protected with a cover which avoids the ingression of foreign particles into the fan. Free circulation of the cooling air must be ensured. The exhaust air - also the exhaust air of other machines next to the drive system - must not be immediately taken in again.
5. Electrical connection
All operations must be carried out only by qualified and skilled personnel when the low-voltage machine is at standstill and when the machine is de-energized and protected against unintentional restart. This also applies to auxiliary circuits (e.g. brake, encoder, separate fan).
Check safe isolation from the supply!
If the tolerances in EN 60034-1; IEC 34 (VDE 0530-1) - voltage ±5 %, frequency ±2 %, waveform, symmetry - are exceeded, more heat will be generated and the electromagnetic compatibility will be influenced.
Observe the indications on the nameplate, operating notes, and the connection diagram in the terminal box.
The connection must ensure a continuous and safe electrical supply (no loose wire ends); use appropriate cable terminals. The connection to the PE conductor must be safe. The plug-in connector must be screwed up tightly (to stop).
The clearances between bare, live parts and earth must not fall below: 8 mm at V rated
≤ 550 V, 10 mm at V rated
≤ 725 V, 14 mm at V rated
≤ 1000 V.
The terminal box must be clean and dry; foreign particles, dirt and moisture affect operation. All unused cable entries and the box itself must be sealed against dust and water. For the trial run without output elements, lock the key. Check brake operation before the commissioning of low-voltage machines with brakes.
6. Operation
Vibration severities v rms
≤ 3.5 mm/s (P rated
≤ 15 kW) or 4.5 mm/s (P rated
> 15 kW) are acceptable when the clutch is activated. If deviations from normal operation occur, e.g. increased temperature, noise, vibration, find the cause and, if necessary, contact the manufacturer. Switch-off the machine in problematic situations.
If the drive is exposed to dirt, clean it regularly.
Do not switch-off the protection devices, not even for trial runs.
Integrated temperature sensors do not provide full protection. If necessary, limit the maximum current. Connect the function blocks to the option switch-off after several seconds of operation at I > I rated
, especially if blocking may occur.
Shaft seals and bearings have a limited service life.
Regrease the bearings using the relubrication facility while the low-voltage machine is running. Observe the saponification number. If the grease drain hole is sealed with a plug (IP54 drive end; IP23 drive end and non-drive end), remove the plug before commissioning. Seal the bore holes with grease. Replace the prelubricated bearings
(2Z-bearings) after approx. 10.000 h - 20.000 h, at the latest however after 3 - 4 years. Observe the manufacturer’s instructions.

Drive systems can reach dangerous overspeeds (e.g. setting high field frequencies for motors and machines which are not suitable):
• The controllers do not offer any protection against these operating conditions. Use additional components for this.
During parameter set transfer, the control terminals of the 9300 controller can have undefined states!
Therefore the plugs X5 and X6 must be removed before transfer. Thus it is ensured that the controller is inhibited and all control terminals have the defined state ”LOW”.

Warning!
•
When a new parameter set is loaded, the controller is reinitialised and acts as if it was connected to the mains:
– System configurations and terminal assignments may be changed. Ensure, that your wiring and drive configuration correspond to the settings of the parameter set.
•
Only use terminal X5/28 as a source for controller inhibit! Otherwise the drive may start accidentally when changing to another parameter set.
Tip!
The RDY message is not displayed while the parameter set is loaded since the controller cannot be operated then.

For terminal control
You can change to other parameter sets via e.g. the digital inputs X5/E1...X5/E5.
After mains connection, the controller reads parameter set 1 first. Then, the terminals are evaluated and the desired parameter set is loaded. A LOW-HIGH edge at input DCTRL-PAR-LOAD (” Load parameter set” ) is not necessary in this case:
•
One or two ditital inputs must be assigned to ” Select parameter set” in every parameter set.
– Determine the source(s) for ” Select parameter set” under C0880. The signal names are:
DCTRL-PAR*1 and DCTRL-PAR*2.
•
One digital input must be assigned to ” Load parameter set” in every parameter set:
– Determine the source for ” Load parameter set” under C0881.The signal name is:
DCTRL-PAR-LOAD.
•
These inputs must have the same assignment in all parameter sets which you want to use.
•
The controller reads the terminals assigned with ” Select parameter” as a binary code. The input DCTRL-PAR*1 is the first input, the input DCTRL-PAR*2 is the second input (e.g. E1 = first input, E2 = second input).
– The signal must be applied constantly at the terminals for at least 10 ms so that the parameter set to be loaded is recognized correctly.
– Terminal signals to select parameter sets:
Parameter set 1

Error analysis with the history buffer
•
The history buffer is used to trace faults.
•
Error messages are stored in the order of their occurence.
Double-click the entry ” Diagnostics dialog” in the parameter menu of GDC to open the dialog box
Diagnosis 93xx:
History buffer
3.2.1
Structure of the history buffer
•
The history buffer provides 8 memory locations. The fields under ” Fault history” show the memory locations 2 to 7.
•
The fields under ” Actual fault” show memory unit 1. It contains information on the active fault.
– The first memory unit is written only after the elimination or acknowledgement of the active fault. This entry eliminates the last fault from the history buffer so that it can no longer be read.
•
The history buffer holds three information units for every error that had occurred: c d e c
Fault recognition and reaction d
Time of the fault e
Frequency of the fault
The following table shows the assignment of information and codes.

Contains the fault detection for every memory location and the reaction to the fault.
– e.g. ” OH3 TRIP”
– With a fieldbus, the faults are indicated by a fault number.
(
LEERER MERKER, column 2)
Please note:
•
For faults occuring at the same time with different reactions:
– Only the reaction of the fault with the higest priority (priority = TRIP
→
Message
→
FAIL-QSP
→
Warning) is entered into the memory.
•
For faults occuring at the same time and with the same reaction (e.g. 2 messages):
– Only the fault which occurred first is entered.
Time
d
•
Contains the times when the faults occurred
– e.g. ” 1234567 s”
– Reference time is the mains switch-on time (see dialog box
Diagnosis 93xx, top right field)
Please note:
•
If a fault is immediately followed by another several times, only the time of the last occurrence is stored.
