Product Description:
The KDA 2.1-100-3-AY0-W1 spindle drive is designed specifically to run with a rated current of 100 Amperes, with the ability to handle heavy loads continuously without generating much heat. This drive is made by Bosch Rexroth Indramat to operate with a DC bus voltage of 300V, which is used to supply the required voltage for smooth and efficient operation at different loads.
This drive supports an analog ±10V speed command input signal that allows accurate analog control, thereby enabling high precision speed variation by means of external control systems. This spindle drive is intended for an acceptable ambient operating temperature of +5°C to +45°C, permitting operation in controlled indoor environments common to industrial applications. For storage and shipping, this drive can handle a temperature range of -30 °C to +85 °C, providing for secure handling in varying logistical conditions. The KDA 2.1-100-3-AY0-W1 spindle drive has an auxiliary encoder input for allowing integration with secondary encoder systems to monitor or provide feedback in multi-axis or synchronous applications. This drive is also furnished with synchronous encoder signal support that increases positioning precision and supports applications in systems that require high-speed synchronization.
This spindle drive’s cooling mechanism relies on forced air circulation through a heatsink blower, which inhibits internal heat buildup and enables it to tolerate peak loads over long-duty cycles. This drive’s heatsink blower is powered with a 220V AC supply at 50-60Hz for compatibility with common power sources and to minimize further electrical conversion requirements. The KDA 2.1-100-3-AY0-W1 drive can be installed at a maximum of 1,000 meters above sea level to enable reliable operation without loss of performance in facilities with moderate altitudes. This spindle drive’s mechanical mounting access weight is 1.7 kilograms, which needs to be factored when determining total load distribution for secure installation.
Frequently Asked Questions about KDA 2.1-100-3-AY0-W1:
Q: How does the auxiliary encoder input help in motion control systems?
A: It provides enhanced positional feedback for improved accuracy. This enables better synchronization in multi-axis applications.
Q: Why is synchronous encoder support included in KDA 2.1-100-3-AY0-W1?
A: It allows for high-precision control in systems where motor and load must operate in perfect sync. This feature is essential in applications like robotics and CNC.
Q: How does the forced cooling mechanism improve drive performance?
A: Forced cooling prevents heat buildup during continuous operation. This enables the drive to sustain high loads without thermal shutdown.
Q: What role does the ±10V analog input play in drive control?
A: It allows proportional control over spindle speed using external analog signals. This simplifies integration into legacy or analog-dominated control systems.
Q: Why is the drive’s operation limited to 1,000 meters elevation?
A: Above this height, air density decreases, affecting cooling efficiency. The unit is designed for optimal airflow performance under standard atmospheric pressure.
