Product Description:
Bosch Rexroth Indramat creates this KDA 3.1-100-3-AYD-W1 spindle drive that works with analog speed signals and digital position commands for machining and industrial automation systems. The firm is respected for making equipment that lasts and functions consistently in industrial sectors.
The KDA 3.1-100-3-AYD-W1 spindle drive functions with an AC supply for the heatsink blower rated at 220 V AC by supporting efficient forced cooling. The unit is equipped with auxiliary encoder inputs that allow both auxiliary and synchronous feedback to maintain a stable drive response under varying load conditions. Its cooling system is handled by a dedicated heatsink blower which aids in supplying proper continuous airflow with an operating temperature range from -30 to +85 degrees Celsius. The DC bus voltage is specified at 300 V by enabling reliable power transfer for drive operation. In terms of structural classification, the drive follows design number 1 by maintaining consistency with standard engineering layouts. The position command interface is a digital 16-bit parallel type that facilitates precise positional control signals between the motion controller and the unit. The rated current capacity is given as 100 A during peak functions.
The KDA 3.1-100-3-AYD-W1 spindle drive is a member of series 3 by providing a link within corresponding assemblies. For speed control, the input accepts an analog ±10 V signal that works as a standard reference range in applications. The unit’s voltage must remain less than 50 V before servicing with the option of short circuiting if necessary and a copper line with a cross-sectional area of at least 6 mm² is required for safety compliance. It can be installed easily at an elevation level above 1000 m above sea level.
