Product Description
The Rexroth Indramat KDA 3.3-150-3-A0D-U1 is a KDA 3 series main spindle drive controller. It is designed for speed control and position control applications. The drive is cooled by forced cooling: a built-in blower forces air across the heatsink which is attached to the back side of the drive. The blower on the KDA 3.3-150-3-A0D-U1 requires 115 Volts AC power input. Rated current for the KDA 3.3-150-3-A0D-U1 is 150 Amps and the continuous current rating for the drive is 90 Amps. The DC bus on the drive carries a 300 Volts DC voltage during drive operation. This voltage must be allowed to discharge during drive maintenance. Failure to do so can lead to electric shock. The drive power should also be switched off during maintenance related activities. Weight of the KDA 3.3-150-3-A0D-U1 drive is approximately 17.4 kilograms.
The blower on the KDA 3.3-150-3-A0D-U1 weighs 4.2 kilograms. The KDA 3.3-150-3-A0D- U1 supports integrated analog speed command. With conventional CNC controllers, it is possible to output the drive internal rotor position or the spindle position as an incremental encoder signal. Auxiliary encoder input is not supported on the KDA 3.3-150-3-A0D-U1. The drive also supports an auxiliary interface for 16-bit parallel digital command value. A serial interface is available for storing and loading parameters onto a connected computer. The KDA 3.3-150-3-A0D-U1 is programmed from the control panel which is located on the front of the drive. The operating parameters and drive firmware are stored on an AS programming module. Enclosure of the drive is IP 10 rated and is designed for installation inside an industrial cabinet. All installation and operation related activities should be performed by trained personnel.
