The Ferrocontrol DARC S02-00-0A belongs to the DARC series of digital axis controllers from Ferrocontrol and controls brushless synchronous motors with a rated current of 2.0 A. In the DARC, positioning and servo amplifier are combined in one unit.
Function within the DARC system
The axis controller is connected to a DARC supply module (V05 or V15) and converts the 560 V DC link voltage provided there into the three-phase motor voltage. Several servo modules can be coupled in parallel on the DC link, up to eight drives per supply module. The controller receives positioning commands via the fieldbus from the supply module with interpolation processor or, for simple tasks, directly via the RS232 interface.
Control and feedback
Control is fully digital with online-optimised control parameters. Rotor position and actual speed are acquired via the robust resolver feedback with up to 16-bit resolution. Hardware version 00 denotes the basic version with resolver interface. Sinusoidal pulse-width modulation ensures smooth running even at the lowest speeds, and IGBT power stages with a 2 × 8 kHz switching frequency ensure minimal losses and quiet operation.
Further features
- Fully digital parameterisation, service replacement without readjustment
- Motor temperature monitoring via PTC sensor or temperature switch
- Relay contact for the holding brake (30 V / 1 A)
- Opto-isolated control inputs, plain-text diagnostics via the higher-level control
- Compact design, protection class IP20, CE-compliant

Proven in machine building
The DARC S02-00-0A is used by machine manufacturers such as Rapid, Urban, IMA Schelling, Kiesling, Siempelkamp, Actual, Perforex, MAW Nottmeyer and Josting. Please state the machine type and part number with your inquiry so that we can supply the controller with matching firmware and parameter sets (Plug and Work).
Procurement from Finke Maschinen
The DARC S02-00-0A is available from Finke Maschinen as a refurbished unit with warranty or as a tested used part; new units only from remaining stock while supplies last. The DARC series has been discontinued by the manufacturer and cannot be reordered; its successor is the DARC2 series. Benefit from short delivery times, fair prices and expert advice from our Ferrocontrol and Eckelmann specialists.
