Frequently Asked Questions
For Bosch Rexroth Indramat MDD025B-N-100-N2G-040FD1, what’s a typical B2B use case and integration tip?
It’s often paired with Rexroth digital drives in compact multi-axis stations (gantries, tool changers, small robotics) where 10,000 rpm enables high linear speeds with fine reducers. Use the motor’s stored ID data to auto-parameterize the drive and verify duty against the MDD025 torque-speed curve before final gearing.
For digital drive controllers, what signals must the cable set carry beyond the three phases?
Plan for the integrated PTC temperature sensor and brake supply leads within the power connector, plus the 12-pin feedback connector for the resolver. The drive must monitor the PTC for thermal protection and control the brake coil directly.
What mounting considerations arise from the 40 mm centering diameter and compact 025/B frame?
The pilot (centering) diameter is your primary locating feature; match tolerance to achieve runout targets before tightening the IM B5/B14 flange. Compact geometry eases fits in tight envelopes but leaves less room for cable bend—plan clearance accordingly.
How should I route power/feedback cables given the Side B connection direction?
MDD feedback angle connectors are supplied to exit on Side B; plan bend radius and strain relief so motion doesn’t load the connector. Side labels (A/B) are fixed in the manual to avoid wiring ambiguity during installation.
Is the 1.0 Nm blocking brake sufficient to hold vertical loads during power-off?
It’s a holding brake sized to secure a stationary axis, not a dynamic safety brake—verify that reflected load torque (including gravity and gear ratio) stays below 1.0 Nm with margin. For long storage (>2 years), Rexroth prescribes a brief “re-seating” procedure to restore brake performance.
