Product Description:
The KDA 3.1-100-3-D0D-W1 signifies the Indramat' KDA Spindle Drives that supplies a continuous current of 100 A and provides sustained current capacity for prolonged spindle workloads. This also sets steady thermal load expectations for internal electronics. Three axes are integrated which allows coordinated control of multiple spindle channels and supports simultaneous multi-spindle machining processes. By offering a supply voltage of 3 x 380-480 V AC, +10%/-10%, 50/60 Hz, it enables connection to common three phase mains and tolerates supply variation for stable power to the inverter stage.
|Control voltage at 24 V DC powers logic and interface circuits and ensures a stable low voltage supply for sensors and gate driver logic. This equipment with internal fan cooling circulates air inside the module and maintains component temperatures under continuous duty. SERCOS, analog and digital communication interfaces permit deterministic motion control and versatile integration with fieldbus and analog command sources. Drive's power loss of approx. 1100 W defines the thermal energy that must be removed and guides ventilation and heat extraction design. Measuring a dimension of 550 x 75 x 275 mm set the installation envelope and inform panel layout and rack planning.
|Spindle drive KDA 3.1-100-3-D0D-W1 lists a mass of approx. 13 kg which allows handling loads and mounting support requirements for panel installation. The protection certification of IP20 denotes safety against solid objects over 12.5 mm. It further indicates that liquid ingress protection requires additional enclosure measures. A DC bus voltage of 300 V provides the intermediate link voltage for the inverter stage and aligns the module with common DC bus systems. An ambient operating range of 0° to 45°C establishes the environmental limits for reliable operation and informs room climate control. A 16 bit parallel speed command value supplies fine resolution for speed setpoints and supports precise velocity adjustment. The module comes with an auxiliary encoder input for 1 V sinusoidal signals accept high resolution feedback and enables feedback control spindle positioning.
Frequently Asked Questions about KDA 3.1-100-3-D0D-W1:
