Project Planning Manual | Rexroth MKE Synchronous Motors Electric Drivesand Controls7 Options and Accessories7.1 Motor EncoderEncoder data memoryTo control the motor speed and / or to position the motor, the drive control devicemust know the current motor position.To achieve this, the integrated encoder system provides the drive control devicewith the corresponding signals. The drive control devices are capable of transmittingthe positional value thus determined to a superordinate CNC or SPS.The encoder electronics is equipped with a data memory where the motor typename, the control loop parameters and the motor parameters are filed. Rexrothdrive control devices read out this data. This ensures●●quick and easy startup,adaptation between the motor and the drive control device without the riskof damage to the motor.The following encoder variants are available for MKE motors:| Bosch Rexroth AG 61/131Options and AccessoriesTypeDescriptionMeasuringmethodSystem accuracyType of positiondetectionPosition resolution on themotorG 1)Digital resolver feedback (RSF)Relative MKE037, 047K 1)Digital resolver feedback (RSFwith integrated multiturn absoluteencoder)Induktive±8 angular minutesAbsolute (morethan 4096 revolutions)3 x 2 13 = 24576MKE0984 x 2 13 = 32768Information / RevolutionN 1)P 1)Digital servo feedback (HSF)Digital servo feedback (HSF withintegrated multiturn absolute encoder)±0.5 angularminutesRelativeAbsolute (morethan 4096 revolutions)MKE098, 118512 x 2 13 = 4194304Information / RevolutionA 2)C 2)Optical singleturn Hiperface encoderOptical multiturn Hiperface encoderOptical±80 angularsecondsAbsolute (morethan 1 revolution)Absolute (morethan 4096 revolutions)128 x 2 13 = 1.048.576Information / RevolutionB 2)D 2)Optical singleturn EnDat 2.1 encoderOptical multiturn EnDat 2.1 encoderResolver feedback (RSF)±20 angularsecondsAbsolute (morethan 1 revolution)Absolute (morethan 4096 revolutions)2048 x 2 13 = 16.777.216Information / Revolution1)for drive control devices Diax 04, EcoDrive 03, DuraDrive2)for IndraDrive drive control devicesFig.7-1: MKE motor encoderFurther information and details on the encoder types are described in the following.Provided for relative indirect position detection. Replaces separate incrementalencoders on the motor.Characteristics of the resolver feedback: After a voltage failure orafter the first POWER ON, the axis must first always be moved toits reference point, before the processing can begin.
