Product Description:
The KDA 3.2-100-3-APD-W1 Spindle Drive has a rated current capacity of 100 A to power motors with high energy requirements in continuous-duty operations. This drive is built by Bosch Rexroth Indramat, and it’s suitable for manufacturing and automation environments.
Under operation, this drive operates within an ambient temperature range of +5 °C to +45 °C. It weighs a total of 16.6 kg, and supports panel or cabinet mounting without needing additional structural support or alteration to conventional enclosures. Its constant current rating is 70 A to provide stable output levels in normal operating conditions without overloading the internal elements. The KDA 3.2-100-3-APD-W1 spindle drive runs with a DC bus voltage of 300 V, which allows for effective voltage regulation of motor phases during frequent acceleration and deceleration processes. This drive has an integrated auxiliary encoder input, programmed for second motor or spindle feedback, that improves real-time positional sensitivity and motor synchronization on two-axis applications. A digital 16-bit parallel auxiliary interface is provided for position command input for direct, rapid, and precise data communication with external motion controllers. The KDA 3.2-100-3-APD-W1 drive meets humidity class F, allowing for stable performance and safeguarding against moderate humidity conditions in regular factory environments.
This KDA 3.2-100-3-APD-W1 drive has a transport temperature range of -30°C to +85°C that protects and maintains component integrity in stored or shipped non-operating environments. This drive’s specialized heatsink blower implements forced cooling, efficiently dealing with heat dissipation during heavy load operations and sustaining thermal safety conditions. This heatsink blower is powered by an AC supply input of 220V at 50–60 Hz, and this power configuration is easily available. The analog +/-10V speed command input ensures the spindle motor gets voltage-based speed signals of high precision for systems with high-resolution analog control.
