Drive dimensioningIn order to carry out an accurate drive dimensioning process, you can use our configuringsoftware, the »Drive Solution Designer«.With the «Drive Solution Designer«, you can design the drive both quickly and to a highquality. The software contains profound and proven expertise with regard to drive applicationsand mechatronic drive components.Please get in touch with your Lenze representative.

The dimensioning is suitable for:• kinematic profiles• operating modes S1, S2, S3, S6 ^ 66• simple linear speed profiles, not for S-curves or similar

The following 3 elements are taken into consideration in the dimensioning process:

Drive functionOn the basis of the values required for the process that are specified, a drive is selected, forwhich all operating points are within the speed-torque characteristic curve of the motor.As a result, a motor with a suitable speed and an inverter with a sufficient maximum currentare selected. Further limits (maximum speed, installation height...) are specified in tables.

Mechanical strengthOn the basis of the occurring forces and torques, a drive is selected that has a sufficientmechanical strength (endurance strength for the periodically occurring torques and fatiguestrength for the sporadically occurring torques).

Thermal dimensioningFor the inverter, the thermal dimensioning process is carried out on the basis of thecontinuous inverter current or on the basis of the continuous torque from the motor-invertercombination, which can be reached.The motor is thermally dimensioned on the basis of the mean speed and the effective torque.The mean speed of the drive should not exceed the values specified.

If dimensioning processes are complex or reach limit loads, please refer to yourLenze representative.

BrakesOptionally the motors can be ordered with a spring-applied brake as holding brake.

CAUTION!They may not be used as safety elements (particularly with hoist axes) without additionalmeasures being implemented.The brakes used are not fail-safe brakes in the sense that prospective disruptive factors, e.g.oil ingress, can lead to a reduction in torque! The brakes must only be used as holding brakes for holding the axes at a standstill or in the

deenergised state. The brake must not be used as a service brake.

CAUTION!If no suitable voltage (incorrect value, incorrect polarity) is applied to the brake, the brake willbe applied and can be overheated and destroyed by the motor continuing to rotate.

Motor supply cablesIf long motor supply cables are used, pay attention to the ohmic voltage drop along the cableand compensate for it with a higher voltage at the input end of the cable.The following applies to Lenze system cables:

[V]U[V] U [V] 0.08 l [m] I [A][A] [m]

U V Resulting supply voltageUB V Rated voltage of the brake

lLg m Cable length

IB A Rated current of the brake

NOTICE The brakes become active when the supply voltage has been switched off (closed-circuit

principle). When using the brakes purely as holding brakes, virtually no wear occurs on the friction

surfaces. The friction surfaces must always be free from oil and grease because even small amounts

of grease or oil will considerably reduce the braking torque.

NOTICEIn case of travel axes, the compliance of the permissible ratio of mass inertia load/brakemotor (JL/JMB) ensures that the permissible maximum switching energy of the brake will notbe exceeded and at least the values given for the emergency stop functions from the givenspeed (see rated data) are applied.For hoist axes, the load torque resulting from the weight acts additionally. In this case, thespecifications for (JL/JMB) do not apply.

To simplify matters, the friction energy per switching cycle can be calculated using the formulabelow and must not exceed the limit value for emergency stops, which depends on theswitching rate:

ML nM Load torque

The shortest operating times of the brakes are achieved by DC switching of thevoltage and an external suppressor circuit (varistor or spark suppressor).Without suppressor circuit, the operating times may increase. A varistor/ sparksuppressor limits the breaking voltage peaks. It must be ensured that the powerlimit of the suppressor circuit is not exceeded. This limit depends on the brakecurrent, brake voltage, disengagement time and the switching operations pertime unit.Furthermore the suppressor circuit is necessary for interference suppressionand for increasing the service life of the relay contacts (external, is notintegrated into the motor).

It is not possible to readjust the brake.

Rated data

Engagement and disengagement times apply to rated voltage (± 0 %) andsuppressor circuit of the brakes with a varistor with DC switching. Without asuppressor circuit, the times may be longer.The currents are the maximum values when the brake is cold (value used fordimensioning the current supply). The values for a motor at operatingtemperature are considerably lower.With 24 V DC brake: smoothed DC voltage, ripple ≤ 1 %.With 230 V AC brake: connection to an integrated rectifier (no cURus possible).Maximum switching energy for each emergency stop with n= 3000 rpm for atleast 300 , and a maximum of 4 emergency stops per hour.

Feedbacks in the environment of functional safetyMotors can perform speed-dependent safety functions for safe speed and/or safe relativeposition monitoring in a drive system by Lenze inverters or Controllers. In case of inverters,these functions are implemented by integrable safety modules and in case of Controllers bythe additionally required Safety Controller.When planning systems/installations of this kind, always observe the following:• When using just one single feedback system in the environment of these safety

applications, the applicable safety engineering standard IEC 61800-5-2 (adjustable speedelectrical power drive systems - Part: 5-2: Safety requirements - Functional) stipulatesspecial requirements for the connection between feedback system and motor shaft.

• This is due to the fact that two-channel safety systems at this point in the mechanicalsystem are actually designed as single-channel systems. If this mechanical connection isdesigned with considerable overdimensioning, the standard permits exclusion of the fault"encoder-shaft breakage" or "encoder-shaft slip". As such, the permissible angularacceleration limit values must not be exceeded for the individual drive solutions.

You can find the limit values in the corresponding feedback data of the individual motorranges.

Speed-dependent safety functions

Examples of speed-dependent safety functions:• Safe stop 1 (SS1)• Safe operational stop (SOS)• Safely limited speed (SLS)• Safe maximum speed (SMS)• Safe direction (SDI)• Operation mode selector (OMS) with confirmation (ES)• Safe speed monitor (SSM)• Safely limited increment (SLI)

Temperature monitoring

Thermal detectors PT1000The thermal detector used continuously monitors the motor temperature. The temperatureinformation is transferred to the inverter using the system cable of the feedback system. Thisis not a full motor protection!This makes it possible to determine the motor temperature in the permissible operating rangewith great accuracy.

When supplying the thermal sensors with a measurement current of 1 mA, theconnection between the temperature and the resistance measured applies.

Operating modes of the motorOperating modes S1 ... S10 as specified by EN 60034-1 describe the basic stress of an electricalmachine.

In continuous operation a motor reaches its permissible temperature limit if it outputs therated power dimensioned for continuous operation. However, if the motor is only subjected toload for a short time, the power output by the motor may be greater without the motorreaching its permissible temperature limit. This behaviour is referred to as overload capacity.Depending on the duration of the load and the resulting temperature rise, the required motorcan be selected reduced by the overload capacity.
