REXROTH TDM1.2-30-300-W1 AC Servo Drive – INDRAMAT TDM Series
Imagine a high-speed CNC machining center mid-cycle — spindle at full RPM, axes interpolating at micron-level precision — when the servo drive trips offline. The entire production line halts. Scrap accumulates. Maintenance scrambles for a replacement that must be an exact drop-in, not a substitute. The REXROTH TDM1.2-30-300-W1 is precisely that irreplaceable component: a dedicated AC servo drive engineered to deliver deterministic torque and velocity control in the most demanding motion-control environments. Without it, the machine simply cannot run.
Within the INDRAMAT TDM (Transistor Drive Module) family, the TDM1.2-30-300-W1 occupies the mid-power tier — rated for 30 A continuous output current with a 300 V DC bus — making it the preferred choice for axis drives on mid-to-large CNC machining centers, injection molding machines, and industrial robots. The TDM series established Bosch Rexroth’s reputation for closed-loop servo performance in the 1990s and 2000s and remains one of the most widely installed legacy servo platforms globally, with millions of units still in active service across automotive, aerospace, and precision manufacturing facilities worldwide.
