Digital Drives

Selca supplies complete digital packages composed of CNC, motors and drives.

The digital drives supplied by Selca are produced directly by Dr. JOHANNES HEIDENHAIN.

They have been designed for the high-speed milling applications where the high dynamic and the position control precision are basic and guarantee a very high axis dynamic answer and a precise speed control.

According to the required powers, they can be COMPACT or MODULAR and permit system configurations with a variable axis and spindle number, according to the specific application needs.

The COMPACT configuration foresees:
* a regenerative or non-regenerative power supply and four power modules are contained in a single unit
* an external braking resistor module for the non-regenerative models
* a commutating reactor and a line filter for the regenerative models

The MODULAR configuration foresees:
* regenerative or non-regenerative power supplies
* single-axis and double-axes power modules
* an external braking resistor for the non-regenerative models
* a commutating reactor and a line filter for the regenerative models
* an optional emergency braking module for the regenerative modules
