General

Motors in the 8LV series are available with EnDat encoders as well as resolvers. The encoder system is listed as part of the model number in the form of a 2-digit code (ee).

A resolver is an analog encoder system. Resolvers are particularly robust against vibrations and high operating temperatures. A disadvantage is the low accuracy of 6-10 arcmin. Furthermore, no multi-turn variant with resolvers is possible.

Digital encoders use a serial transfer protocol. This protocol is called EnDat. The EnDat protocol is a developed standard that incorporates the advantages of absolute and incremental position measurement and also offers a read/write parameter memory in the encoder. The embedded parameter chip is stored by B&R in this encoder memory. This data and the B&R ACOPOS systems form a plug-and-play drive solution. Absolute positioning can be used within a revolution with the single-turn variants. A homing procedure is not required because of the absolute position measurement. For applications where the motor covers several revolutions for positioning, a multi-turn encoder that can save up to 65535 revolutions can be used. A solution with a single-turn encoder variant with a homing procedure is also possible.

RE-15-1-J04 resolvers are used in the motors.

EnDat 2.2 encoder

For the advanced, fully digital EnDat 2.2 protocol, the positions are generated directly in the encoder and communicated serially with the drive system. This transfer is very robust in relation to disturbances and is even certified for safety applications.

Digital drive systems and position control loops require fast and highly secure transfer of data obtained from position measuring instruments. In addition, other data such as drive-specific characteristics, correction tables, etc. should also be available. To ensure a high level of system security, measuring instruments must be integrated in routines for detecting errors and be able to perform diagnostics.

The EnDat interface from HEIDENHAIN is a digital, bidirectional interface for measuring instruments. It is able to output position values from incremental and absolute measuring instruments and can also read and update information on the measuring instrument or store new data there. Because it relies on serial data transfer, only 4 signal lines are needed. Data is transferred synchronously to the clock signal defined by the subsequent electronics. The type of transfer used (e.g. for position values, parameters, diagnostics, etc.) is selected using mode commands sent to the measuring instrument by the subsequent electronics.

Output shaft (jj)

The motor/gearbox combinations from the 8LVB series can be delivered with a smooth or keyed shaft end.

Smooth shaft endA smooth shaft end is used for a force-fit shaft-hub connection and guarantees a backlash-free connection between the shaft and hub as well as a high degree of operating smoothness. The end of the shaft has a threaded center hole.
Keyed shaft endA keyed shaft end is used for a form-fit torque transfer with low demands on the shaft-hub connection and for handling torque in a constant direction. The keyways of the gear units of the 8LVB series conform to keyway form N1 in accordance with DIN 6885-1. The end of the shaft has a threaded center hole that can be used to mount machine actuators with shaft end cover plates.

Valid codes: see table "Determining the order code for device options"

Holding brake (jj)

Motors in the 8LV series can be delivered with a holding brake. It is used to hold the motor shaft when no power is applied to the motor.

Nominal speed / Connection type (nn)

The first position (nn) of the two-position code (nn) is the nominal speed. The second position (nn) is the connection type.

The nominal speed (nn) of the motor is specified as the speed class in the order key. Speed class is broken up into steps of 500 [rpm] and begins at 80 VDC operation at A = 500 [rpm]. (Deviations include nominal speed 950 [rpm] as class B = 1000 [rpm] and nominal speed 2100 [rpm] as class D = 2000 [rpm].)

The connection type (nn) of the motor in represented in the order key with nW for double angular built-in connector and nS for single-cable solution (hybrid).
