PLUS A und PLUS B Endstufen

PLUS is the name of a series of ministep bipolar chopper drives, suitable for driving two-phase stepping motors with four, six or eight terminals.

PLUS series drives are housed in a metallic box, 152 x 129 x 46 mm format, suitable for wall mounting.

They do not need external fans: accordingly, they are ideal both for mounting inside a metallic electrical cabinet and for stand-alone applications.

R.T.A. experience, together with a thorough design both of hardware and software, has led to a product offering high reliability, premium performances, great ease of use at competitive costs.

The wide range of available current/voltage values optimizes the use of PLUS series drives with a wide variety of stepping motors and in a large number of applications.

  • Operation at 400, 800, 1600, 3200 and 500, 1000, 2000, 4000 steps/revolution.
  • Electronic resonance damping circuit to ensure acoustic noise and mechanical vibrations reduction at low and medium speed.
  • Wide range of operating voltages and motor phase currents setting. Up to 8 possible equidistant values between INF min. and INF max. can be set by means of DIP-SWITCH.
  • Optically insulated inputs compatible with differential control signals.
  • 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 with thermal sensor.
  • High efficiency CHOPPER with MOSFET final stage output.
  • Operation with built-in oscillator with speed range from 14 to 450 rpm setting by means of DIP-SWITCH.
  • Alarm memory by use of yellow blinking led.
