Indramat TVD

Indramat TVD

The TVD 1.3 system accommodates connected loads from power systems of 3 x AC 380-480V, 50-60Hz, eliminating the need for a transformer. Additional auxiliary units such as the NAM 1.3 are available to suppress reactions on the power system. Moreover, the TVD 1.3 features integrated internal contactors for powering down the drives' power system, ensuring efficient shutdown procedures. Additionally, it incorporates internal DC bus dynamic braking functionality, allowing motors with permanent magnetic fields to be safely brought to a standstill in the event of fault conditions within the drive electronics, enhancing overall system safety and reliability.

- Input voltage: 3 x 380 to 480 volts AC, with a tolerance of ±10%.
- Frequency: 50 to 60 Hertz.
- Incoming power: 300 volt-amperes (VA).

Notable Features

The Indramat TVD system offers a regulated DC bus voltage, ensuring stable operation even under mains undervoltage conditions. It features a charging current limit for the DC bus capacitors, reducing inrush current and prolonging the service life of switching devices in the power system. With the capability to mount up to ten drive modules to one supply module, it offers extreme load capabilities for control voltage. The system is designed for easy servicing, with signal leads connected via plug-in screw clamps. Additionally, the TVD 1.3 is available in two power stages, with options for continuous DC bus power of 7.5 kW or 15 kW, allowing optimal matching to application requirements. Furthermore, the TVD 1.3 boasts overload capabilities for short-duration acceleration of feed and main drives, with maximum possible acceleration power specified in project planning guidelines to ensure safe operation.
