Product Description:
Produced by the globally famous brand Bosch Rexroth Indramat, the variant KDA 3.2-100-3-D0S-U1 identifies as a main spindle amplifier built for machine tool integration. Its rated output current values 100 A which supplies ample drive current for heavy spindle loads and guarantees constant torque delivery. This spindle drive runs at a rated output voltage of 3 x 320 V and is 3-phased, to provide the required voltage levels for stable three-phase motor operation. Also, its input voltage is 3 x 400 V AC ±10%, allowing tolerance to supply fluctuations and supporting grid compatibility across industrial sites.
Input frequency maintains at 50/60 Hz that allows operations on both common industrial mains and global installations. Continuous output power is approximately 32 kVA which supports prolonged spindle operation under steady load and enables continuous machining cycles. The device’s switching frequency is 8 kHz and can yield fine PWM resolution for smoother torque control and reduced motor vibration. Utilizing forced air cooling with an internal fan further maintains thermal stability under sustained loads and prevents thermal trips. Protection class of IP20 indicates prevention against solid objects above 12 millimeters and for this reason it suits enclosed cabinet mounting.
Overload capability is 150% for 60 s that allows short bursts of high torque for machining transients and protects the system during intermittent peaks. Encoder interface supports TTL and SinCos, enabling flexible feedback options for precise speed and position control. Type code KDA 3.2-100-3-D0S-U1 lists fieldbus interface options including PROFIBUS and CANopen to allow networked control and integration with higher level automation. Weight of 35 kg facilitates in handling the equipment and rack planning for control cabinets. With a DC bus voltage of 300 V, the unit provides the drive energy buffer for dynamic torque demands and stabilizes DC link during rapid load changes.
