Understanding Indramat TDM Servo Drives
What Are Indramat TDM Servo Drives?
Although Indramat is no longer an active manufacturer, its TDM servo drives remain in operation across many legacy motion control systems. These drives are known for their:
-
Versatility across multiple industrial applications
-
Precision performance
-
Modular adaptability through personality modules that eliminate the need for factory tuning
-
Durability and longevity, even under rugged conditions
-
Multifunction support, adaptable for complex systems
As part of Indramat’s modular system, TDM drives pair seamlessly with MAC series servomotors to deliver high-speed, closed-loop, rapid-response motion control.
TDM Servo Drive Variants
TDM drives are available in several configurations to suit a range of needs. The most common units include:
| TDM Series | Key Features | Compatible Motors |
|---|---|---|
| TDM 1.2 / 1.4 | Standard operation with X1 bus port | MAC71 – MAC160 |
| TDM 2 – 6 | Wide performance range | MAC63 – MAC112B |
| TDM 1.3 / 3.3 | Safety interlock built-in | Limited use, harder to replace |
The TDM 1.3 and 3.3 units include safety interlocks and are less readily available. Due to limited availability, repair is often more practical than replacement.
Installation Requirements
TDM drives are not designed for standalone use and must be installed inside a control cabinet for proper operation. Key installation considerations include:
-
Minimum clearance of 80 mm above and below the unit for air cooling
-
Use of X1 connection ports to establish a reliable bus communication link
-
Proper grounding and shielding to ensure stable electrical operation
Applications of Indramat TDM Servo Drives
TDM servo drives continue to support numerous applications across industrial sectors, particularly where legacy machinery remains active:
-
Packaging systems
-
Automotive production lines
-
CNC (Computer Numerical Control) machine tools
-
Assembly and robotics automation
Frequently Asked Questions
What power ranges do TDM servo drives support?
TDM drives are primarily designed for low to medium power range applications. Their functionality can be significantly enhanced through the use of personality modules, which tailor the drive to specific motor performance profiles.
Which motors are compatible with TDM drives?
Compatibility is determined by the TDM series:
| TDM Drive | Compatible MAC Motors |
|---|---|
| TDM 1 | MAC71 – MAC160 |
| TDM 2 | MAC63 – MAC93 |
| TDM 3 | MAC63 – MAC112B |
| TDM 4 | MAC21, MAC25, MAC41 |
What is the function of the starting lockout?
The starting lockout is a safety feature that:
-
Allows safe power-down of the motor via a hardware relay
-
Disconnects the output stage from the control electronics
-
Prevents unintentional startups, especially in fault conditions
This is especially useful during maintenance or when replacing parts such as motors or cables.
