62/131 <strong>Bosch</strong> <strong>Rexroth</strong> AG | Electric Drivesand Controls<strong>Rexroth</strong> <strong>MKE</strong> Synchronous Motors | <strong>Project</strong> <strong>Planning</strong> <strong>Manual</strong>Options and AccessoriesResolver feedback (RSF) with integratedmultiturn absolute encoder●●●●When placing the home position circuit breaker and during the reference,note that the resolver's mode of action generates several reset signalsduring a mechanical motor revolution.For <strong>MKE</strong>037 and <strong>MKE</strong>047: 3 reset signals per revolutionFor <strong>MKE</strong>098: 4 reset signals per revolutionAvoid too high a gear ratio or to slight a feed-constant.Provided for absolute indirect position detection within 4096 motor revolutions.Replaces separate absolute value encoders on the motor.The absolute axis position for this encoder variant remains validafter power shut down because of the battery back-up. The nominaldurability of the batterie is about 10 years.Digital servo feedback (HSF)Provided for relative indirect position detection. Replaces separate incrementalencoder on the motor.After a voltage failure or after the first POWER ON, the axis mustfirst always be moved to its home position.Digital servo feedback (HSF) withintegrated multiturn absolute encoderProvided for absolute indirect position detection within 4096 motor revolutions.Replaces separate absolute encoder on the motor.The absolute axis position for this encoder variant remains validafter power shut down because of the battery back-up.Optical singleturn encoderOption A, BMultiturn absolute optical encoderOption C, DThese encoders permit absolute, indirect position recording within one mechanicalrotation. The encoders replace separate incremental encoders on themotor.After a power failure or after the first POWER ON, the axis must firstalways be moved to its home position.Exception: Applications in which the maximum working path is withinone mechanical rotation of the motor.These encoders permit absolute, indirect position recording within 4096 mechanicalrotations. The encoders replace a separate absolute value encoderon the motor. With this encoder version, the absolute position of the axis ispreserved even after voltage switch-off.7.2 Holding BrakesThe holding brake serves to hold the axis when the machine is in a de-energizedstate. In normal operation, use the holding brake only at standstill or for EMER‐GENCY STOP in order to deactivate an axis (n < 10 min -1 ).Please observe the application notes when using holding brakes in chapter9.11 "Holding Brakes (Ex)" on page 90.For technical data and availability of holding brakes, see chapters"Technical data" and "Type codes".
