The motor operates with a nominal current of 10.9 A and a stall current of 15.3 A. Its maximum current reaches 64.6 A, enabling rapid acceleration and deceleration. The torque constant is 1.63 Nm/A, and the voltage constant is 98.44 V/1000rpm. These values indicate efficient torque generation per unit of current.
Additional electrical parameters include a stator resistance of 0.398 Ohm and a stator inductance of 5.6 mH. The electrical time constant is 14.1 ms, while the thermal time constant is 43 minutes. The motor's moment of inertia is 17.9 kg·cm², and its mass is 14.50 kg without brake. These characteristics contribute to precise control and stable performance.
Built-in Feedback and Safety Features
The 8LSA56.ee030ffgg-4 includes an embedded parameter chip for automatic drive identification. This simplifies setup and ensures optimal performance with compatible drives. The motor supports resolver or EnDat encoders, including inductive and optical types. Single-turn and multi-turn options are available, with 32-line resolution.
For functional safety, encoders are available that support safety-related position measurement. This allows integration into safety systems when paired with appropriate drives. The motor's thermal protection uses KTY83-110 (up to rev C7) or AM-PTC1000 (rev C8/C9). The maximum winding temperature is 155°C, but ACOPOS drives limit it to 110°C with EnDat and 130°C with resolver.
Compatibility with ACOPOS Servo Drives
The 8LSA56.ee030ffgg-4 is recommended for use with ACOPOS servo drives, specifically the 017X series. This pairing ensures optimal performance and reliable operation. The motor's parameter chip enables automatic drive identification, reducing commissioning time. The ACOPOS drive also implements STO (Safe Torque Off) for safety functions.
Integration is straightforward with the built-in plug-in connectors, including swivel and SpeedTec types. A single-cable hybrid solution is available, simplifying wiring. The motor's connectors support the speedtec (923) and itec/ytec/htec (723) systems, offering flexibility in connection options.
