Product Description:
The Bosch Rexroth KDA 3.1-050-3-A0I-U1 main spindle drive is developed to provide precise spindle control in automation systems. The drive incorporates into modular machine configurations and offers analog speed control. It is designed for applications that necessitate incremental encoder feedback and analog voltage control.
The KDA 3.1-050-3-A0I-U1 is capable of operating at a continuous current rating of 50 A and is compatible with a DC bus voltage of 300 V. The analog ±10 V input is used to configure the speed setpoint, which enables precise adjustment. The instrument is equipped with an incremental encoder output that facilitates closed-loop speed monitoring. The drive is incapable of accommodating additional encoder inputs. It used a forced cooling system that is powered by an AC voltage of 115 V at 50 to 60 Hz and incorporates a heatsink fan. The permitted ambient operating temperature is between +5 and +45 °C, with reduced efficacy at 55 °C. The temperature range for storage and transportation is -30°C to +85°C. Additionally, it includes a multi-pin interface that may be utilized for programming or diagnostics. The drive is enclosed in a metallic case that includes a handle for rack-mounting and built-in ventilation fins.
The KDA 3.1-050-3-A0I-U1 has a handle that can be used for installation and servicing in modular enclosures. There are ventilation holes in the case that allow the drive to stay cool all the time. The X6 terminal block, which has ports A1, A2, and A3, can connect to either analog or digital signals. An RJ45 interface is used to execute Ethernet or other proprietary communication protocols. As the warning sign indicates, the green part needs to be taken off after the power is turned off to get to the programming module port.
