2 Safety informat ion
2.1 Personnel responsibl e for safety
Operator
l An operator is any natural or legal person who uses the drive system or on behalf of whom
the drive system is used.
l The operator or his safety officer must ensure
– that all relevant regulations, instructions and legislation are observed.
– that only qualified personnel works with and on the drive system.
– that the personnel have the operating instructions available for all corresponding
operations.
– that non-qualified personnel are prohibited from working with and on the drive system.
Skilled personnel
Skilled personnel are persons who are - because of their education, experience, instructions, and
knowledge about corresponding standards and regulations, rules for the prevention of accidents,
and operatingconditions- authorizedbythepersonresponsibleforthe safetyof theplant toperform
the required actions and who are able to recognize potential hazards
(seeIEC364, definition for skilled personnel) .
2.2 General safety information
l This safety information is not claimed to be complete. In case of questions and problems
please contact your Lenze representative.
l At the time of supply thedrive system meets the state of the art and ensures basically safe
operation.
l The drive system is a source of danger for persons, for thedrive system itself, and for other
material assets of the operator, if
– non-qualified personnel work with and on the drive system.
– the drive system is used inappropriately.
l The drive systems must be designed such that they perform their functions after proper
installation and with application as directed in non-interfered operation and that they do not
cause hazards for persons. This also applies for their interaction with the complete plant.
l Make sure by appropriate measures that in case of failure of the drive system no material
damage is caused.
l Operate the drive system onlywhen in proper state.
l Retrofittings, modifications, or redesigns of the drive system are basically prohibited. In any
case, Lenze must be contacted.
l The compact units must not be adjusted in standstill.

3 Technical data
l The most important data are indicated on the nameplate.
l Further technical data are listed in the product catalogues.
3.1 Product features
3.1.1 Design
Drive systems have a modular design. They consist of:
l Simplabelt attachment units
l Reduction gearboxes (helical gearboxes, worm gearboxes, helical worm gearboxes, or
helical bevel gearboxes)
l Three - phase AC motors to IEC standard
l Adjustment facilities
l Speed displays
3.1.2 Method of operation
(seeFig. 1 and Fig. 2 )
The three-phase AC motor (11BA)drives the mechanically adjustable variable speed pulley (1BA)
whichdrives the spring-loaded variablespeed pulley( 2BA)via theV-belt (3BA). Thispulley is fitted
onto thedrivingshaft of thereduction gearbox (12BA). Thevariablespeed pulleysandthe V-belt are
covered by the housings (4BA and 5BA).
The speed is adjusted via the adjustment facilities (6BA, 7BA, 8BA), i.e. by turning the handwheel
or operating the adjusting motor to move thepulley flange of themechanically adjustable variable
speed pulley(1BA)inthe axialdirection. The speed is indicated bymeans of thespeed indicatorin
the handwheel or a DC tacho or an impulse recorder and a display.

3.3 Operating conditions
3.3.1 Temperatures
The permissible temperature range is determined by the following:
l Thetorquetobetransmitted(→ dimensioning).
l The lubricant specification of the gearbox considering the oil temperature expected during
operation (see nameplate and/or Operating Instructions of the gearbox).
l The thermal class of the motor considering the motor temperature expected during operation
(seenameplate and Operating Instructions of the motor).
The operating temperature is determined by the power loss, the ambient temperature and the
cooling system!
3.3.2 Ambient conditions
l Gearboxes are protected against dust and spray water.
l Motors according to their enlosure (seenameplate and/or Operating Instructions of the
motor).
l Ambient media - especially chemically aggressive - can destroy shaft seals and coatings
(plastics) . Abrasive media may endanger shaft seals.

4.2 Installation
4.2.1 Preparation after long storage
Carefully remove the anti-corrosion agents from output shafts and flange surfaces.
4.2.2 General information on the assemblyof drive systems
l Take the necessary safety measures prior to any operations:
– Disconnect the machine from the mains, ensurestandstill of the machine and avoid any
machine movement.
– Check the proper state of the drive system. Never install and set-up damaged drive
systems.
– Check the combination of drive function and machine function. Check the direction of
rotation.
l The mounting surfaces must be even, without torsion, and free of vibrations.
l Align the drive system on the mounting surfaces exactly with themachine shaft to be driven.
l Ensurethat the assembly is without torsion, to avoid additional load.
l Compensate minor misalignment by using suitable flexible couplings.
l Upport the reaction torque appropriately.
l Fixings of accessories and attachments must be secured against loosening.
l We recommend bonding screw connections.

4.3.2 Connection of the remote- control motor
Stop!
The remote-control motor must only be operated when the main motor is running. For testing the
functions at standstill, the momentary-contact switches must only be touched briefly.
1. Connect the remote-control motor according to the circuit diagram ( Fig. 3).
2. Check the direction of rotation in inching mode:
– Touch switch S1: the contact pin must move towards the flange.
– Touch switch S2: the contact pin must move in theopposite direction.
– If the pin does not move as indicated, reverse the motor polarity.

The drive must only be commissioned by skilled personnel!
5.1 Before you start
Ensurethat the driveis not connected to mains and does not rotateunintentionally . Please check:
l Is the mechnical fixing o.k.?
l Are the electrical connections o.k.?
l For gearboxes with ventilation:
Is the plug removed from the breather screw?
Commissioning
5.2 During operation
Check the drive periodically during operation and take special note of unusual noises or
temperatures, leakages, loose fastening elements, and the state of the electrical cables. If any
interference occurs, proceed according to the troubleshooting list in chapter 7. If it is not possible
to eliminate the interference, please contact the Lenze Service.

Maintenance

6 Maintenance
6.1 Maintenance intervals
Stop!
With drivesystems: Please observethe maintenance intervals of theother drive components, too!
l Wide V-belts have a natural wear which depends on several factors:
–On-time
– Load type
– Speeds
– Ambient temperature
As a guide value Lenze recommends to check the wide V-belt for wear and fissures every 4 to 6
months and replace it, if necessary.
l Variable speed pulleys are maintenance-free.
Note!
While checking thewide V-belt Lenze recommends to inspect visually the variable speed pulleys.
Check if themovabledisc canbe moved and the state of the disc face. Run-in grooveson the disc
face caused by wear reduces the belt life.
6.2 Maintenance operations
6.2.1 Replacing the V-belt
Stop!
Only use original Simplabelt V-belts!
Disassembly with U-design (see Fig. 1):
1. Activate the drive and accelerate it to max. speed, then switch off the drive and disconnect it
from mains.
2. Loosen 6 screws (1.16; 1.15)and remove the cover (5BA).
3. Completely open the variable speed pulleys (1BA), pull the V-belt (3BA)over the front edge of
the variable speed pulley (1BA)and remove it when turning the variable speed pulley.
