Product Description:
The model KDA 3.1-050-3-APS-W1 is a reliable main spindle drive unit. It is engineered for precision motion control in CNC and automation environments. The unit supports auxiliary encoder feedback. It features forced cooling and weighs approximately 16.6 kg. It ensures consistent drive performance even in demanding industrial conditions.
This KDA 3.1-050-3-APS-W1 main spindle drive has a rated current of 50 A and operates with a DC bus voltage of 300 V. The auxiliary encoder input allows feedback from either a spindle or a second motor. It uses analog ± 10 V as its speed command input that offers precise response to control signals. The cooling mode of the drive is forced cooling that ensures stable thermal operation during continuous load cycles. The drive has a protection category of IP 10 which offers basic protection against large solid objects. It is compatible with an AC supply source for the heatsink blower rated at 220 V 50 – 60 Hz. The mechanical mounting kit M1-KD weighs 1.7 kg and supports secure and stable installation. The drive is designed to consume 1.2 A from a 24 V load voltage source. It performs reliably in environments where the ambient temperature can reach up to + 55 °C with reduced nominal values. For humidity resistance, it meets Class F standards that ensures durability in varying industrial conditions. These features make it suitable for integration in a wide range of automated machining setups.
The storage and transport temperature range of the Bosch Rexroth KDA 3.1-050-3-APS-W1 main spindle drive is between - 30 °C and + 85 °C. The drive weight of 16.6 kg reflects a compact yet robust design suitable for integration in various machine configurations. It supports analog speed commands which allows seamless interaction with common industrial control systems.
