The One Cable Solution offers the following advantages:
• Significantly reduced wiring effort by eliminating the encoder cable
• For cable lengths up to 50 m, a choke between the drive controller and motor is not necessary
• Advanced safety functions possible (up to SIL2 / category 3, PLd)
• Significantly reduced space requirements by eliminating the encoder plug connector
• Transmission of measured values from the temperature sensor using the EnDat 3 protocol
A motor with the EnDat 3 encoder can be operated only on a SI6 or SC6 drive controller from STOBER.
The EnDat 3 encoder has the following features:

Notes
• The encoder code is a part of the type designation of the motor.
• FMA = Version with fault exclusion for mechanical coupling.
• MTTF = Average time before dangerous failure. MTTF values greater than 100 years were reduced in
accordance with DIN EN ISO 13849.
• PFH = Probability of a dangerous failure per hour
• The EnDat 2.2 EBI 1135 encoder requires an external buffer battery so that absolute position informa-
tion is retained after the power supply is turned off (AES option for STOBER drive controllers).
• Multiple revolutions of the motor shaft can be recorded only using multi-turn encoders.
