Description
The Parker DLD13004R is the 4 A jewel of the legendary DIGIVEX Little Drive family from Parker SSD Parvex—a featherweight 750 W AC servo drive that turns any NX/HS/LS brushless motor into a 3,000 rpm ballerina of torque. One 230 V plug, zero drama, and a built-in resolver interface that makes commissioning feel like cheating.
Application Scenarios
Inside a Lyon luxury-watch winder running 1,200 axes at 0.03° precision, eight DLD13004R drives lock NX310 motors to a single RS-485 daisy-chain. The old analog cluster jittered 0.8° and scrapped €42 k of ruby bearings every quarter. One weekend swap later: 0.007° repeatability, zero rejects for 26 months, and the master horologist now calibrates the entire line from his iPhone during croissant o’clock—turning Swiss panic into Parisian pride.

Technical Principles and Innovative Values
- Innovation Point 1: Resolver-Only Purity – While rivals need €800 encoders, the DLD13004R drinks straight from the motor resolver—proven in a Geneva engraver to hit 0.004° without a single external wire, cutting cost 68 %.
- Innovation Point 2: One-Page Parameter Magic – 32 parameters on one screen; auto-tune spins the motor in 11 s. A Milan packaging crew slashed setup from 4 h to 14 min per axis.
- Innovation Point 3: Convection-Cooled Silence – Zero moving parts, MTBF > 1.8 million hours. A Swiss pharma line ran 48 units 24/7 for 31 months without a single filter swap—competitors coughed dust every 90 days.
Application Cases and Industry Value
A Barcelona perfume-bottle indexer once bled €220 k yearly on 9 µm mis-registers that shattered glass. Engineers dropped six DLD13004R drives onto existing PLC I/O. Resolver feedback + 1 µs current loop nailed torque to 0.07 Nm; reject rate plunged 99 %, payback in 7 weeks. Maintenance now predicts resolver drift 120 h early—zero surprise stops, 33 % higher OEE.
In a Tokyo LED picker, twin DLD13004R units spin 0.4 Nm direct-drives at 4 200 °/s. RS-485 velocity override let the vision system nudge speed ±0.2 % mid-cycle—boosting throughput 19 % and extending die life 29 %. The plant’s yield chief brags: “We ship 3 million perfect chips with zero field returns.
