R911287273 (KDA 3.3-100-3-LP0-U1)

Description

The Rexroth R911287273 (KDA 3.3-100-3-LP0-U1), a microcontroller-based digital drive controller, specializes in drive control, monitoring, and diagnostics. Developed to control Indramat 2AD and 1MB series motors, the device features a SERCOS speed command interface and an auxiliary encoder input for secondary motor feedback. This model, however, does not come with a second auxiliary interface. With an air cooling system, the controller includes a 115 Volts AC powered blower that maintains the temperature of the device's heatsink. The R911287273 (KDA 3.3-100-3-LP0-U1) has a 100 Amp output current rating and is built for a 300 Volts DC control DC bus. The controller offers a digital control panel to adjust device parameters. Its operating parameters and firmware are stored on the AS module which can be transferred to a replacement controller to minimize downtime. The device is IP 10 rated and maintains optimal performance between 5 and 45 degrees Celsius at altitudes up to 1000 meters.
