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!

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.

Residual hazards

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.
