Product Description:
The KDA 2.1-100-3-DYS-W1 Main Spindle Drive supports high performance in demanding machining applications. The drive is microcomputer controlled and designed for precision. It ensures accurate synchronization between drive and motor functions. The compact design and professional configuration make it suitable for advanced machine tools.
The KDA 2.1-100-3-DYS-W1 main spindle drive operates within an ambient temperature range of + 5 °C to + 45 °C. It can work at reduced ratings up to + 55 °C. The drive delivers a rated current capacity of 100 A. The measuring voltage consumption is 160 mA at ± 15 V. The main spindle drive features a DC bus voltage rated at 300 volts. This voltage level is utilized as the intermediate link between the rectifier and the inverter stages of the drive system. It provides the necessary potential for the power conversion process. It uses an auxiliary RS 232 C interface protocol for system communication. The drive’s power connection cables depend on rated motor current. The short term or intermittent overloads are supported in motor operations. INDRAMAT parameters synchronize drive and motor for machine tool compatibility. The drive specific parameters influence operating characteristic curves during usage. These parameters are pre set to match required operational characteristics. The cooling is forced through an external blower unit. The cooling fan unit LE4 weighs 4.2 kg. The blower requires 220 V supply at 50 to 60 Hz frequency.
The KDA 2.1-100-3-DYS-W1 main spindle drive offers a microcomputer control that ensures precise spindle speed regulation. The parameter settings optimize drive efficiency under varying load conditions. The synchronization enhances stability during heavy cutting operations. Proper cooling maintains consistent thermal conditions for long term reliability. The electrical and mechanical design ensures consistent spindle performance.
