Indramat DKC

The ECODRIVE drive controllers are distinguished by their digital and intelligent drive system capabilities, which are primarily based on the type of interface they offer for higher-level control systems. Depending on the application needs, the range of ECODRIVE controllers is tailored to fit specific requirements.

The DKC01.1 drive controller is versatile and can be employed in various operational modes. It can function as a servodrive equipped with integrated position control, making it suitable for precise motion applications. It is also capable of operating with an analog speed interface while providing integrated actual position detection, which is essential for applications requiring accurate speed control. Additionally, it can be used with a stepper interface or as a servodrive with an electronic gearbox function, offering flexibility in motion control tasks.

In contrast, the DKC11.1 drive controller is noted for its cost-effectiveness and is designed to serve as a servodrive that comes with an analog speed interface and integrated actual position detection. This makes it a practical choice for applications that need reliable speed control without the high costs associated with more advanced features.

BZM Auxiliary Bleeder Module

The BZM auxiliary bleeder module is used in conjunction with the DKC drive when the regenerative power and energy generated by the mechanics exceed the absorption capacity of the bleeder built into the drive. The addition of the BZM module enhances the capability of the DKC drive to handle excess regenerative energy.

This is particularly useful in configurations where multiple drive controllers are connected via the DC bus circuit, as it allows for either a single drive and auxiliary bleeder module connection (1 DKC+BZM), several drive controllers (up to 6 DKCs), or a combination of several drive controllers and auxiliary bleeder modules (up to 6 DKC+BZM) to effectively manage the regenerative energy within the system.

Designation Symbol Unit Value
Continuous bleeder output (continuous regenerative power when drives are braked) PBD,BZM kW 1
Peak bleeder power (peak regenerative power) PBM,BZM kW 40 (perm. load cycle on for 1s, off for 40s)
Maximum feedback energy WMAX,BZM kWs 40
Control voltage between X4/1 and X4/4 UN,BZM V DC 24 V ±20%
Current consumption of the 24 V connection IN,BZM mA 90

CZM Auxiliary Capacitance Module

The CZM Auxiliary Capacitance Module is utilized with DKC drives, specifically the DKC01.1-040-7-FW and DKC11.1-040-7-FW models, to manage regenerative energy efficiently during braking. When the drive is braked, the rotary energy from the mechanics is converted into regenerative energy in the DC bus of the DKC drive. This energy can either be dissipated as heat via the built-in bleeder module or the auxiliary bleeder, or it can be stored in the CZM Auxiliary Capacitance Module. When stored, this energy is not wasted but is instead available to be reused for future acceleration procedures. Utilizing the CZM module in this way helps to reduce the power dissipated in the control cabinet, resulting in lower energy consumption for the system.
