Frequently Asked Questions
How does Digital Servo Feedback (DSF) affect homing and position retention after power loss?
DSF provides high-resolution relative position; variants may include an integrated multi-turn absolute encoder, enabling absolute referencing with compatible drives. If your DSF is relative-only, plan a repeatable homing routine at startup.
There’s no blocking brake on my unit—what should I consider for vertical or safety-critical axes?
Without a holding brake, gravity loads must be secured via external brakes (gearbox, clamp) or safe torque-off strategies; some 090C variants offer ~6.5 Nm brakes if needed. Validate stopping/holding requirements in the risk assessment before enabling motion.
What cable and shielding practices are recommended for DSF feedback and power wiring?
Use Rexroth-specified pre-made cables (IKL/IKG) or equivalents, maintain shield continuity, and keep feedback separate from power to reduce EMI. Follow the controller manual’s bend-radius and grounding rules to avoid encoder noise.
Are there environmental or protection-class considerations for factory floors with coolant mist or dust?
The MDD housings are specified per DIN 40050/IP conventions; with a shaft seal and correct cabling, typical variants are suited for industrial environments, but verify the exact IP rating in your data sheet. Add splash guards if coolants can impinge directly on the shaft area.
Is the Bosch Rexroth Indramat MDD090C-N-030-N2L-130GB0 interchangeable with other 090C speed/feedback options during service?
Within the MDD090C family, torque class and mechanics are similar, but nominal speed, brake option, and DSF variant (relative vs absolute) differ and must match the drive parameter set. Confirm code string (speed, brake, feedback, centering) before substituting.
