Understanding Indramat TDM Servo Drives

3 October, 2023


Indramat TDM servo drives are legacy drives, and there are no new servo drives of this series from the manufacturer today. The company is defunct, although its products are still operated in the present-day motion control systems. These servo drives are noted for their versatility which allows them to be used for multiple applications. Precision is another key highlight of these servo drives. The servo drives can be equipped with personality modules to eliminate the need for tuning them in the factory. They have a very rugged profile and feature a long lifespan, and encompass multifunction capabilities.   

TDM drives come in a wide range of configurations. The most common types comprise the TDM 1.2 and 1.4 units and  the TDM 2, 3, 4, 5 and 6 units. There are also some safety interlock units such as the TDM 1.3 and 3.3 units. These safety interlock units are limited in number and hence it is better to repair them rather than trying to replace or exchange them when needed. The drives can be used along with MAC servomotors to offer a rapid-response servo drive.

The TDM servo drives are intended to be used only after installing them inside a control cabinet. There must be a clearance of at least 80mm above and below the drive for its cooling air inlets and outlets. Their X1 connection ports can be used to establish a bus connection.

Applications of TDM Servomotors

TDM servo drives are used in different types of applications. These drives are primarily deployed in

  • Packaging industries
  • Automotive industries
  • Computer numerically controlled machine tools


What are the power ranges supported by TDM servo drives?

TDM servo drives are designed to support low and medium power ranges. However, their versatility and accuracy of operation can be increased by connecting personality modules.

What motors can the TDM servo drives be used with?

TDM1 servo drives can be used with the MAC71 to MAC160 range of servomotors. The TDM2 series of servo drives are operated with MAC63 to MAC93 series of servomotors. The TDM3 drives work in conjunction with MAC63 to MAC112B motors, while the TDM4 drives function with MAC21, MAC25 and MAC41 servomotors.

What does the starting lockout of the TDM servo drives do?

The starting lockout integrated into the TDM servo drives helps in powering down the associated motor safely by using a simple switch. This switch incorporates a relay in the hardware that is responsible for disconnecting the output stage from the associated control electronics. The starting lockout prevents the motor from unintentional startups triggered by a fault.
