Product Description:
Bosch Rexroth Indramat in the KDA Spindle Drives series added a new variant KDA 3.2-100-3-A00-U1 and carries protection class of IP20. This mandates enclosure installation to prevent it from any sort of harm. The device’s ramp up time T ≤ 10 ms enables very fast torque build up which limits transient deviation during spindle start sequences. Compatible devices include the Rexroth Indramat’s servomotors that match electrical and control parameters for simplifying parameter transfer and commissioning.
A frequency of 50/60 Hz maintains smooth integration with standard regional power systems while maintaining accuracy in timing for control processes. Offering a maximum output power of 100 W, the unit sets the available spindle capacity. Designed for panel mounting, the device assembles securely within a control cabinet, making wiring and routine servicing straightforward. Depending on configuration, motor’s feedback can be managed through a resolver or encoder, giving flexibility between absolute position tracking or incremental signal feedback to match specific control needs. Internal fan cooling circulates air within the module, thus preventing heat buildup and enabling reliable long-term operation.
The KDA 3.2-100-3-A00-U1 specifies supply voltage of 3 x 400/460 V AC for stable DC bus charging. The communication interface SERCOS provides live exchange of data for motion control and synchronization. Additionally, the rated output current of 3.2 A sets the continuous current available to the motor and defines conductor sizing and thermal planning. Its chopper frequency of approx. 8 kHz determines switching cadence and balances switching losses with current ripple. The three axes indicate support for three coordinated channels. Weighing around 4.2 kg, the module defines panel support and handling needs during installation. Operating temperatures from 0 to 45°C (non-condensing) limits ambient conditions for reliable operation and cabinet ventilation planning.
