The Rexroth Indramat R911265757 (KDA 3.3-150-3-A0S-W1) is a digital drive microcomputer controller that pairs with motors from Indramat's 2AD and 1MB series. With high stiffness, a broad speed range, and positioning features, this drive has a rated output current of 150 Amps and a continuous output current of 90 Amps. It supports a speed command value of analog 10 Volts and includes an auxiliary serial interface compatible with RS-232 protocol. The drive does not support auxiliary encoder input, and uses forced air across a heat sink to stay cool. The blower requires 220 Volts AC. The drive is paired with a motor and matched to a machine tool using parameters stored on an AS module. To replace the drive, these parameters can be transferred from the old to the new drive, avoiding reprogramming and minimizing downtime. Compatible with cold, moderate, and dry-warm climates, the R911265757 (KDA 3.3-150-3-A0S-W1) performs best when the relative humidity is below 70%.
