2Safety instructions
2.1Personnel responsible for safety
Operator
ƒ An operator is any natural or legal person who uses the drive system or on behalf of
whom the drive system is used.
ƒ The operator or his safety officer must ensure
– that all relevant regulations, instructions and legislation are observed.
– that only qualified personnel work 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 − because of their education, experience, instructions,
and knowledge about corresponding standards and regulations, rules for the prevention
of accidents, and operating conditions − are authorised by the person responsible for the
safety of the plant to perform the required actions and who are able to recognise potential
hazards.
(See IEC 364, definition of skilled personnel)
2.2General safety information
ƒ This safety information does not claimed to be complete. In case of questions and
problems, please contact your Lenze representative.
ƒ At the time of delivery the drive system meets the state of the art and ensures safe
basic operation.
ƒ The drive system is a source of danger for persons, for the drive system itself, and for
other material assets of the operator, if
– unqualified personnel works with and on the drive system,
– the drive system is used inappropriately.
14
ƒ The drive systems must be designed such that they perform their functions after
proper installation and with application as directed in fault−free operation and that
they do not cause hazards for persons. This also applies for their interaction with the
complete plant.
ƒ Be sure to take appropriate measures in the case of drive system failure so that no
material damage occurs.
ƒ Operate the drive system only when it is in a proper state.
ƒ Retrofittings, modifications, or redesigns of the drive system are basically
prohibited. Lenze must be contacted in all cases.

The DISCO variable speed drive is a planetary gearbox, where all the functional parts run
in an oil bath. The planets, located in the pinion cage, rotate around the driving inner
sun. The speed and the force flow are transmitted from the drive shaft to the inner sun.
The flat, double−coned planets are driven by the inner sun, simultaneously rolling along
the outer rings which are fixed in the housing. So the planets don’t only rotate about
their own axes but also about the inner sun. They thus move the pinion cage with them,
which has a fixed connection with the output shaft.
The speed setting is altered by means of an adjustment spindle through rotating one of the
three outer rings on the housing. This moves the planets to a different radius of rotation,
depending on the size of the air gap between the outer rings. In this way, steplessly
adjustable output speeds are achieved. Supplementary gearboxes, in the form of single or

multi−stage helical, conical or worm gearboxes, can be used to adjust output speed to the
requirements of the application.
(Stop!
The DISCO must only be changed to a fasterspeed while it is running!
Otherwise, the DISCO could be damaged!
Changing to a slowerspeed is allowed while the DISCO is standing still.

3.3Operating conditions
3.3.1Temperatures
ƒ DISCO: permissible ambient temperature −15 bis +40°C
ƒ Rear−mounted gearbox (see Operating Instructions for the gearbox)
ƒ Motor (see temperature class for the motor)
The operating temperature is determined by the power loss, the ambient temperature and
the cooling system!
3.3.2Ambient conditions
ƒ DISCO variable speed drives are dust and hose−proof.
ƒ Motors corresponding to their degree of protection (s. nameplate and/or operating
instructions of the motor).

Mechanical installation
Storage
4Mechanical installation
}Danger!
Only transport the drive with transport equipment or hoists which are suitable
for this load (see transport weights, chapter 3.2). Ensure a safe fixing. Avoid
shocks!
The motors attached to the gearbox are partially equipped with eyebolts.
These are exclusively determined for motor/gearbox mounting and
dismounting and must not be used for the complete geared motor!
4.1Storage
If you do not install the DISCO at once, please ensure proper storage conditions.
ƒ Up to one year:
– Without special measures in dry, dust−free enclosed rooms without direct sunlight.
– Store DISCO with ventilation in a manner that the breather screw is at the top.
– Shafts and bright surfaces are delivered with protection against corrosion.
ƒ Over one year:
– Please consult the factory.
4.2Installation
Mount the drive systems on an even surface, free from distortion. If they are mounted on
a baseplate, then the baseplate must also be mounted without distortion. If this is not
done, then stresses appear in the gearbox housing and have a bad effect on the parallel
alignment of the shafts and thus on the bearing and tooth alignment.
The output shaft of the drive system must be well aligned with the machine shaft that is
to be driven. Small inaccuracies can be compensated by using a flexible coupling.
Couplings, gear wheels, sprockets etc. must only be fixed by screwing to the shaft ends of
the drive system. Driving them on can damage the ball bearings.

Electrical connections must only be carried out by skilled personnel!
{Danger!
Always earth the drive!
If it is not possible to earth it via attached items (e.g. the motor) then the
gearbox must be earthed!

5.2Electrical adjusting device
(Stop!
The DISCO must only be changed to a fasterspeed while it is running!
Otherwise, the DISCO could be damaged!
Changing to a slowerspeed is allowed while the DISCO is standing still.
1. Connect the electrical adjustment device as shown in the circuit diagram (Fig. 2).
Ensure the right polarity of the adjustment motor!
2. It is vital to carry out a functional check in order to avoid damages to the DISCO.
– Check the positions of the adjustment motor and the limit−switch box, see page 6
Position of system blocks".
5.2.1Operational check

6.1Before switching on
Check:
ƒ Is the mechanical fixing o.k.?
ƒ Are the electrical connections o.k.?
ƒ Are all rotating parts and surfaces that may become hot protected against contact?
ƒ For gearboxes with breathing:
– Is the plug removed from the breather screw?

)Note!
Rear−mounted gearboxes must have separate ventilation, ^ Operating
Instruction of the gearbox!
6.2During operation
(Stop!
During running−in, raised temperatures may occur over a period of 2 − 8 hours.
ƒ During operation, check the drive periodically and take special care of:
– unusual noises or temperatures,
– leakages,
– loose fixing elements,
– the condition of the electrical cables.
ƒ If any interference should occur, proceed according to the troubleshooting list in
chapter 8. If the interference cannot be eliminated, please contact the Lenze Service.
