Sprint DC Drives

kW Range: 5 - 980kW Three phase
0.37 - 11 kW Single Phase

Voltage Supply: Up to 690V Three phase


DC motors can produce full torque at low speeds and therefore it remained an industry standard long after AC motors were brought on the market with frequency inverters. However now days DC drives are supplied only for replacement of older obsolete drives. Our Unico drives can replace the DC motor applications with the same response. This means changing the motor as well.

2 and 4 quadrant drives are available as well as compact drives.

Additional Components:

The Buffer card is a compact interface product for signal processing and amplification. The card has five independent channels with a large variety of uses. E.g. multi setpoint systems, closed loop control, signal buffering etc.

For more advanced applications the PLA drive can be used which includes.

  • Diameter calculator
  • Taper tension calculator
  • Torque compensation for inertia and friction
  • Latch with set, reset, clock and data inputs
  • Batch counter with roll-over facility
  • 4 change over switches
  • 3 input digital decoder with 8 programmable output values
  • 4 Quadrant parameter profiler with Linear, square, cubic or 4th power profiling laws
  • Motorised pot simulator with power loss memory
  • 2 high performance PID's with gain profiling
  • 2 Summers with inverting scaling clamping and hysterisis.
  • 2 Filters with precision time constants from milliseconds to 30 secs
  • Delay timer with roll over facility
  • Linear or 'S' ramp with independent up down rates for forward and reverse
  • 4 comparators with programmable hysterisis and aperture option
  • 8 Multifunction blocks with: AND, OR, INVERT, SIGN CHANGE, RECTIFY, COMPARE

Communications Protocols:

Profibus, DeviceNet, CC-Link, EtherNet/IP, Modbus and CANopen.

Power Saving:

DC Motors are not efficient and we recommend replacing them with AC motor and Drive sets.


Centre winding macros, spindle orientation and a fully controllable field allow you to control DC motors in a wide range of industrial applications. The PL/X also includes PL Pilot, a windows based, configuration and monitoring software package.

The PLA is also compatible with drive.web. The drive.web distributed control technology uses Ethernet and powerful graphical tools to provide robust, Programmable Peer Control (PPC) for drives and systems. The drive.web technology is infinitely scalable and cost effective for systems of any size of complexity. For typical motor control systems, it beats using any PLC on cost, performance and easy of use.
