BIPOLAR CHOPPER - X MIND
GENERAL DESCRIPTION
X MIND is the name of a series of ministep bipolar chopper drives suitable for driving two-phase stepping motors with four, six or eight terminals.
X MIND series drives are
housed in a metallic box, 180 x 173 x 53 mm. format, suitable for wall mounting. They can be connected directly to the main AC supply (110 to 230 Vac) avoiding, in many cases, the need for a transformer.
The wide supply range eases the use of this drive in different applications and countries.
The ministep operation, connected with a further electronic resonance damping facility, ensures low acoustic noise and a reduced amount of motor mechanical vibrations.
Optically insulated and differential input/output signals ease interfacing with the most commonly used control systems and ensure high noise immunity.
R.T.A. experience, together with a careful design for these specific purposes, has led to a component offering high reliability, best performances, great ease of use at competitive costs.
TECHNICAL FEATURES
Operation at 400, 800, 1600, 3200 and 500, 1000, 2000, 4000 steps/revolution.
Operation directly from the main AC supply (extended range from 110 to 230 Vac)
Motor phase currents setting by means of a DIP-SWITCH up to four possible equidistant values, between INF min and INF max values indicated below.
Optically insulated inputs compatible with differential control.
Automatic current reduction at motor standstill.
Possibility to switch off motor current with an external logic signal.
Protection against a short circuit at motor outputs.
Protection against under-voltage and over-voltage.
Overheating protection.
High efficiency CHOPPER with IGBT final stage output.
Electronic resonance damping circuit to ensure acoustic noise and mechanical vibrations reduction at low and medium speed.

Working practices are changing rapidly with the onset of new technology.
Working environments are changing too.
Space
is precious.
The comfort, safety and well-being of highly skilled workers is paramount.
This is why CMS have developed the ISODesk, a progressive new concept in workplace furniture.
ISODesk is a modular system designed to provide an ergonomic alternative to conventional workstations and meet the requirements of the modern production and clean room environments in the Telecommunications, Research & Development and Biotechnology fields.
Five standard work-surface sizes are available, all at a standard desk height of 765mm (30.6 in).
The lightweight all aluminium construction features heavy duty castors for ease of movement and all shelving and accessories are ESD compliant.
The ability to choose between active, passive or rigid vibration isolation systems and the choice of three ranges of breadboards with nominal or enhanced damping further increases the flexibility of the system.
Features
Range of Adaptable Accessories to Personalise the Working Area.
Faraday Enclosure Accessory Reduces Thermal Variations and Electromagnetic Interference.
Optimization of Available Space
Full or Partial Damping to Eliminate or Reduce the Effects of Vibration.
Effective Cable Management.
Clear Lines of Sight and Communication.
Maximum Comfort and Legroom.
Minimal Eye and Muscle Strain.
