8LSA46.R0045D000-0 Sizes
8LSA46.R0045D000-0 three-phase synchronous motors are available in seven different sizes (2 through 8). They have different dimensions (especially flange dimensions) and power ratings. These different sizes are indicated by a number represented by (c) in the model number. The larger the number, the larger the flange dimensions and power rating for the respective motor.
Type E is only available upon request.
8LSA46.R0045D000-0 Motor encoder systems
8LSA46.R0045D000-0 three-phase synchronous motors 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). 163 8LSA46.R0045D000-0 three-phase synchronous motors
8LSA46.R0045D000-0 Analog and digital transfer
The encoders operate with 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. In EnDat 2.1 analog/digital sampling, a very fine resolution is achieved by the evaluation modules developed by B&R.
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 method is very robust against disturbances and is even certified for safety applications.
