Understanding Indramat DKS Drives

Indramat products continue to be integral components in modern machinery, offering a diverse range of controls, servo drives, motors, power supplies, and more. Among these, the DKS servo drives stand out due to their integrated structure. Essentially, a DKS servo drive encompasses both control and power functionalities in one unit, divided into a control section and a power section. This integration negates the necessity for an external power supply when deploying a DKS drive.

The DKS servo drive is known for its extensive diagnostic features which facilitate easier troubleshooting. Connections for signal cables are made through screw terminals, and any issues with electronic circuitry can be managed by a dynamic brake system that quickly slows down and stops the drive's operations.

Designed for compatibility with a servomotor, the Indramat DKS servo drive is an AC drive that connects to the motor through feedback and power cables, thereby regulating and overseeing the servomotor’s activity.

Components of a Configured DKS Servo Drive

The configuration of a DKS servo drive includes several components:

- Basic servo drive unit

- Software module

- Command interface card

- Configuration label

- Auxiliary plug-in card

The flexibility of the basic unit is augmented through the addition of various cards in slots U1 to U5, enabling customization for specific operational needs. The command interface card options include a SERCOS interface, a positioning card, or an analog interface with either an absolute or incremental encoder or emulator.

Note, new DKS servo drives are no longer produced; only refurbished or factory-remanufactured units are available.

FAQ

What varieties of DKS drives are available?

There are two main versions of DKS servo drives: DKS 1.1 and DKS 1.2. Though both types look the same and offer peak current ratings of 30 A, 50 A, and 100 A, the DKS 1.2 is structurally more robust, supports heavier components, and can utilize an external capacitor bank for high-speed indexing tasks. This makes it a more advanced version than the DKS 1.1.

What factors should be taken into account when replacing a DKS drive?

When it comes to replacing a DKS drive, ensuring an exact match with the previous model is crucial, as using a different model can lead to system downtime and additional repair expenses. To identify the type of DKS servo drive in your system, refer to the type code located on the system’s configuration label.
