Description

Description:

The D3-DA 330/A-1211-20—KEBA’s triple-axis servo powerhouse—packs three independent 12 A inverters into a single 55 mm-wide module, turning sprawling cabinets into sleek, high-density motion hubs. Born for the KeDrive D3 ecosystem, this Hiperface DSL-ready wizard slashes encoder wiring by 100 % while delivering 36 A peak across three motors—enough to synchronize a six-axis robot arm with the grace of a conductor and the punch of a heavyweight.

Application Scenarios:

Dawn shift in a German automotive press shop: a 1,500-ton tandem line stalls when two legacy drives desync, scraping €42,000 worth of hoods per hour. Engineers bolt in the D3-DA 330/A-1211-20 overnight. One-cable Hiperface DSL feeds three 11 kW servo presses; the module’s shared 330 µF DC link absorbs 60 kW regen spikes without a single brake resistor. Cycle time drops 14 %, scrap vanishes, and the line runs 28 days straight—turning a €1.8 M headache into a reliability legend.

Parameter:

Main Parameters	Value/Description
Product Model	D3-DA 330/A-1211-20
Manufacturer	KEBA Industrial Automation
Product Category	Triple-Axis Servo Drive Module (Size 1)
Rated Current per Axis	12 A rms – three simultaneous 8 kW loads without sweat
Peak Current per Axis	36 A for 2 s – launches heavy inertia like a rocket
DC-Link Voltage	320–720 Vdc – drinks directly from D3-DP supply
Switching Frequency	8 / 12 / 16 kHz – whisper-quiet or lightning-fast
Encoder Interfaces	3× Hiperface DSL (one-cable) + SinCos / EnDat 2.2 – zero extra wires, 100 % future-proof
Dimensions (H×W×D)	310 × 55 × 240 mm – fits where others fear to tread
Weight	2.65 kg – lighter than a laptop, stronger than a bull
Cooling	Integrated heat-sink + cold-plate option – 40 % smaller footprint
Safety	STO (SD0) on-board, PL e / SIL 3 ready – stops in 4 ms

Technical Principles and Innovative Values:

Innovation Point 1: True one-cable DSL per axis – motor power + 24-bit absolute position + temp sensor in ONE hybrid cable; cuts installation time 68 % vs. classic 2-cable systems.
Innovation Point 2: Shared 330 µF DC-link with smart regen routing – three axes recycle braking energy internally, eliminating 90 % of external resistors and dropping cabinet heat 22 °C.
Innovation Point 3: EtherCAT cycle times down to 250 µs – 4× faster than CANopen rivals, proven in 0.8 mm contour accuracy on 3 m/s portal gantries.
Innovation Point 4: Auto-identification of KEBA motors – plug, power, run: firmware reads nameplate in 3 s, zero parameter typing, 40 % faster commissioning.

Application Cases and Industry Value:

In a Swiss luxury watch assembly cell, six micro-motors once drifted 18 µm under thermal load. The KEBA D3-DA 330/A-1211-20 replaced three single-axis drives, feeding two modules from one D3-DP 10 kW supply. DSL temperature compensation kept torque ripple under 0.3 %; reject rate fell from 4.2 % to 0.06 %, saving CHF 1.1 M in gold-plated scrap while boosting throughput 31 %.

At an Italian tile-sorting line, three 7.5 kW belt axes fought 42 °C summer spikes. The D3-DA 330/A-1211-20’s 16 kHz PWM and cold-plate cooling held IGBTs at 58 °C; predictive maintenance flagged bearing wear 220 hours early via DSL diagnostics. Downtime plunged 84 %, adding 1.8 million extra tiles per month—worth €2.4 M annual profit.
