2.1 General safety and application notes for Lenze motors

(to: Low-Voltage Directive 73/23/EEC)
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 qualified, skilled personnel (observe EN 50110-1 (VDE 0105-100); IEC 60364). Improper handling may cause severe injury to persons or damage to material assets.
Synchronous machines induce voltages at open terminals during operation.
Application as directed
These low-voltage machines are intended for industrial and commercial installations. Theycomplywith theharmonized standardsof the EN 60034 (VDEO53O)series. Theiruse in hazardous areas is prohibited unless they are expressly intended for such use (follow additional instructions).
Degrees of protection ≤ IP23 are only intended for outdoor use when applying special protective measures. Air-cooled designs are rated for ambient temperatures from -15 °C and -10 °C to +40 °C and altitudes ≤ 1000 m a.m.s.l., from -20 °C to +40 °C without brake or with spring-operated brake, non-ventilated or with integral fan, 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 machinesare componentsfor theinstallationinto machinesas definedin 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 guaranteed that factors which cannot be influenced, such as oil ingression because of a defective A-side shaft seal, do not cause a torque reduction.
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 r ing 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).
8
Remove theshipping bracesbefore commissioning. Reusethem forfurthertransports. For storage of low-voltage machines ensure a dry, dust-free and low-vibration (v mm/s) environment (damage while being stored). Measure the insulation resistance before commissioning. If the values are ≤ 1kΩ per volt of rated voltage, dry the winding.

Installation
Ensurean evensurface, solidfoot orflange mountingandexactalignmentifadirectclutch isconnected.Avoid resonanceswith therotational frequency anddouble mainsfrequency which may be caused during 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 appropriatetools tomount or removebelt pulleys andclutches (heatgeneration!) and cover them with a touch guard. Impermissible belt tensions must be avoided (technical list).
The machinesare half-key balanced.The clutch mustbehalf-key balanced, too.The visible outstanding part of the key must be removed.
If required,provide pipe connections.Designs with shaft endat bottom mustbe protected witha coverwhichpreventstheingression offoreign particlesinto thefan. Freecirculation of thecooling air mustbe ensured. Theexhaust air -also the exhaust airof other machines next to the drive system - must not be taken in again immediately.
Electrical connection
2
All operations must only be carried out by qualified and skilled personnel when the low-voltage machine is atstandstill and when the machine isde-energizedand 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) -v oltage ±5 %, frequency ±2 %, wave form, 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 bolt tightly (to stop).
The clearances between blank, live parts and earth must not fall below 8 mm at V V, 10 mm at V
The terminal box must be clean and dry; foreign particles, dirt and moisture disturb operation. All unused cable entries and the box itself m ust be sealed against dust and water. For the trial run without output elements, lock the key. Check brake operation before commissioning of low-voltage machines with brakes.

Operation
Vibration severitiesv when the clutch is activated. If deviations from normal operation occur, e.g. increased temperatures, noises, vibrations, 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, n ot even for trial runs.
Integrated temperature sensors do not provide full protection. If necessary, limit the maximum current. Connect the function blocks such that the machine switches off after several seconds of operation at I > I
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 greasedrainhole is sealed with a plug (IP54 driven end; IP23 driven end and non-driven end), remove the plug before commissioning. Seal the bore holes with grease. Replace the prelubricated bearings (2Z bearings) afterapprox. 10,000 h-20,000 h, atthelatest however after3- 4 years. Observe the manufacturer’s instructions.

General safety and application n otes for Lenze controllers
Application as directed
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 accordingto EN 61000-3-2. The documentationcontains information about the compliance with the limit values to EN 61000-3-2.
When installing drive controllers into machines, commissioning of these controllers (i.e. the star ting 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 drive controllersmeet the requirements of the Low-VoltageDirective 73/23/EEC. The harmonised standards of the EN 50178/DIN VDE 0160 series apply to the controllers.
The technical data as well as the connection conditions can be obtained fr om the nameplate and the documentation. They must be strictly observed.

Warning: Drive controllers are products with restricted availability according to EN
61800-3. Theseproducts can causeinterferences in residential premises.If controllers are used in residential premises, corresponding measures are required.
Transport, storage
The notes on transport, storage and appropriate handling must be observed.
The climatic conditions according to EN 50178 must be observed.
Installation
The controllers must be installed and cooled according to the regulations given in the corresponding documentation.
Ensure carefulhandling andavoid mechanical overload.Do notbend any componentsand do not change the insulation distances during transport and handling. Electronic components and contacts must not be touched.
Drive controllers contain electrostatically sensitive components which can easily be damaged byinappropriate handling. Donot damage ordestroy any electricalcomponents since this could mean hazards to your health!

General safety and application n otes for Lenze controllers
Electrical connection
When working on live drive controllers, the valid national regulations for the prevention of accidents (e.g. VBG 4) must be observed.
Carry outthe electrical installationincompliance with thecorresponding regulations (e.g. cable cross-sections, fuses, PE connection). More detailed information is given in the corresponding documentation.
Notes about wiring 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.
In the case of a malfunction (short circuit to frame or earth fault), Lenze controllers can cause a DCresidualcurr ent in theprotective conductor. If an earth-leakage circuitbreaker (residual current device) is used as a protective means in the case of direct or indirect contact, only an e.l.c.b. of type B may be used on the current supply side. Otherwise, another protective measure such as separation from the environment through double or reinforced insulationor disconnection from the mainsby means ofa 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 hasbeendisconnected from the voltage supply, alllivecomponents 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.
NoteforUL approvedsystemswithintegratedcontrollers: ULwarnings arenotes thatonly apply to UL systems. The documentation contains special UL notes.
Safe standstill
The V004 variant of the 9300 and 9300 vector controllers, the x4x variant of the 8200 vector controllers and the ECSxAxxx axis modules support the ”safe standstill” function, protectionagainstunexpected start-up,according tothe requirementsof AnnexI No. 1.2.7 of the EC Directive ”Machinery” 98/37/EC, DIN EN 954-1 C ategory 3 and DIN EN 1037.

If no suitable voltage (incorrect size, incorrect polarity) is applied to the brake, the brake is applied and can overheat and be destroyed by the motor which continues to run.
Theshortestoperatingtimes of thebrakes areachieved by switchingthe voltageon theDC sideand asuppressorcircuit(varistor orspark suppressor).Withoutsuppressorcircuit,the operating times may increase. A varistor/spark suppressor limits the breaking voltage peaks. It must be observed that the power limit of the suppressor circuit is not exceeded. It is dependent on the brake current, brake voltage, disengagement time and the switchings per time unit.

3.3.1 Spring-operated brakes
The spring-operated brakes can be used as holding and/or service brakes. Ifused asservice brake, the permissible friction energy must not be exceeded; otherwise it would destroy the brake. Permissible operating speeds and ratings Emergency stops from a higher speed are possible, but wear increases with high switching energy.
E
Spring-operated brakes catalogue.
Stop!
In any case, the friction surfaces must be kept free of lubricant and grease, since even small amounts can drastically reduce the braking torque.
The use as a pure holding brake results in only minor wear at the friction surfaces. Emergency stops or the use as service brake creates wear at the friction surfaces, and the abrasion of the wear parts creates dust. The Lenze spring-operated brake BFK 458 can be adjusted up to 5 times, while the BFK 418, 457 and 460 cannot be adjusted (for details

9 Maintenance/repair

9.1 Maintenance intervals

ƒ The motors are generally maintenance-free, except for the lubrication of the spindle.
ƒ Wear occurs only at bearings, spindles and seals.
– Check spindle, bearings for running noises (no later than approx. 15,000 h).
ƒ To avoid overheating, regularly remove the deposit build-up on the drives.
ƒ It is recommended to regularly perform an inspection after approx. 50 operating
hours. This allows for early identification and removal of irregularities or faults.

9.2 Maintenance operations

9.2.1 Adjustment of resolver for synchronous servo motors
The resolver from Lenze is adjusted so that the faultless operation is ensured without adjustment at the drive controller.
If the resolver is twisted, e.g. through working on the motor, you must r eadjust it or perform a rotor adjustment at the drive controller.
ƒ For the rotor adjustment, the motor must turn without load at the drive controller
ƒ Resolver adjustment
Stop!
ƒ
Ensure that no foreign bodies can enter the inside of the motor!
ƒ
Perform all work at the drive system only in the de-energised state!
ƒ
Separate drives from the electrical supply!
ƒ
Hot motor surfaces, up to 140 °C. Observe cooling times!
ƒ
Remove the load from the motors or secure loads acting upon the drive!
ƒ
Do not pull the plug if the machine is active!

You must determine the actual winding temperature at a surface temperature > 140 °C:
ƒ Measuring method: 4-phase resistance measurement at motor power terminal
ƒ The resistance measurement must be performed as quickly as possible after
switching off and stopping the servo motor.
Procedure
1. Unplug power connector X10, with terminal box design disconnect power supply between inverter and motor.
2. Measure the resistance between the following contacts or terminals: – Connector X10:
Contacts 4↔5, 5↔6and6↔4
– Terminal box X11:
Terminals 1↔2, 2↔3and3↔1
3. The respective mean value from the three measurements corresponds to the respective double phase resistance (star connection).

After disassembling the motor end guard, the spindle can be traversed by hand. In an emergency situation, the cover can be removed and the motor shaft can be turned with a 10-mm wrench.

9.3 Repair

ƒ It is recommended to have all repairs performed by Lenze Service.
ƒ Delivery of spare parts is available upon request.
Stop!
With opened end guard, the encoder system is unprotected - the enclosure is cancelled. Look out for sensitive components!
Ensure correct seating of the seals during the assembly!

Standards:
EN 60204-1, IEC 204-1 EN 60034, VDE 0530, IEC34
Explanation to the EMC Directive (89/336/EC)
With mains operation at sinusoidal alternating voltage, asynchronous motors meet the requirements of the EC Directive. “Electromagnetic compatibility” 89/336/EWG under consideration of the standards EN 80081-1 and EN 50082-2.
With inverter or p ower converter operation, you must observe the EMCnotes of the inverter or p ower converter manufacturer.
If you are using shielded motor supply cables, the shielding is most effective if it is connected with the earth potential of the motor with the greatest possible surface area (e.g. PG gland made out of metal).
