Residual hazards

Even if notes given are taken into consideraon and protecve measures are implemented,

the occurrence of residual risks cannot be fully prevented.

The user must take the residual hazards menoned into consideraon in the risk assessment

If the above is disregarded, this can lead to severe injuries to persons and damage to

property!

Product

Observe the warning labels on the product!

Dangerous electrical voltage:

Before working on the product, make sure there is no voltage applied to the power terminals!

Aer mains disconnecon, the power terminals will sll carry the hazardous electrical voltage for the me given next to the

symbol!

Electrostac sensive devices:

Before working on the product, the sta must ensure to be free of electrostac charge!

High leakage current:

Carry out xed installaon and PE connecon in compliance with:

EN 61800−5−1 / EN 60204−1

Hot surface:

Use personal protecve equipment or wait unl the device has cooled down!

Protecon of persons

•The product does not provide any safety-related funcons.

-A higher-level safety system must be implemented.

-Provide addional monitoring and protecve equipment complying with the safety

regulaons applicable in each case.

•The power terminals may carry voltage in the switched-o state or when the motor is

stopped.

-Before working, check whether all power terminals are deenergized.

•Voltages may occur on the drive components (e.g. capacive, caused by inverter supply).

-Careful earthing must be carried out at the marked posions of the components.

•There is a risk of burns from hot surfaces!

-Provide protecon against accidental contact.

-Use personal protecve equipment or wait unl the device has cooled down!

-Prevent contact with ammable substances.

•Risk of injury from rotang parts.

-Before working on the drive system, ensure that the motor is at a standsll.

•There is a danger of unintenonal start-up or electric shocks!

•Installed brakes are no fail-safe brakes.

- torque may be reduced by disrupve factors that cannot be inuenced such as

ingressing oil.

Motor protecon

•Version with plug:

-Never disconnect the plug when energized. The plug could be destroyed.

-Switch o the voltage supply or disable the inverter prior to disconnecng the plug.

•Installed thermal detectors are no full protecon for the machine.

-Limit the maximum current if necessary. Parameterize the inverter so that it will be

switched o aer several seconds of operaon with I > Irated especially if there is a

danger of blocking.

-The integrated overload protecon does not prevent overloading under all condions.

•The fuses are no motor protecon.

-Use a current-dependent motor protecon switch.

-Use the built-in thermal detectors.

•Excessively high torques cause a fracture of the motor sha.

-Do not exceed the maximum torques according to the technical data on the

nameplate.

•Lateral forces on the motor sha are possible.

-Align the shas of motor and driven machine exactly to each other.

Drive dimensioning

In order to carry out an accurate drive dimensioning process, you can use our conguring

soware, the »Drive Soluon Designer«.

With the «Drive Soluon Designer«, you can design the drive both quickly and to a high

quality. The soware contains profound and proven experse with regard to drive applicaons

and mechatronic drive components.

Please get in touch with your Lenze representave.

The dimensioning is suitable for:

•kinemac proles

•operang modes S1, S2, S3, S6 ^ 67

•simple linear speed proles, not for S-curves or similar

The following 3 elements are taken into consideraon in the dimensioning process:

Drive funcon

On the basis of the values required for the process that are specied, a drive is selected, for

which all operang points are within the speed-torque characterisc curve of the motor.

As a result, a motor with a suitable speed and an inverter with a sucient maximum current

are selected. Further limits (maximum speed, installaon height...) are specied in tables.

Mechanical strength

On the basis of the occurring forces and torques, a drive is selected that has a sucient

mechanical strength (endurance strength for the periodically occurring torques and fague

strength for the sporadically occurring torques).

Thermal dimensioning

For the inverter, the thermal dimensioning process is carried out on the basis of the

connuous inverter current or on the basis of the connuous torque from the motor-inverter

combinaon, which can be reached.

The motor is thermally dimensioned on the basis of the mean speed and the eecve torque.

The mean speed of the drive should not exceed the values specied.

If dimensioning processes are complex or reach limit loads, please refer to your

Lenze representave.
