The Integrated Guitar Solution: DC input for DC brush, sinusoidal and trapezoidal motors

The Solo Guitar is an integrated solution designed to simply and efficiently connect Elmo's Guitar servo drive directly to an application.

The solution consists of the Guitar together with a convenient connection interface that either reduces or eliminates development time and resources when designing the PCB board for an application.

Solo Guitar Highlights:

  • The Solo Guitar series of digital servo drives is designed to deliver the highest density of power and intelligence.
  • The Solo Guitar is designed for OEMs. It operates from a DC power source in current, velocity, position and advanced position modes, in conjunction with a permanent-magnet synchronous brushless motor, DC brush motor, linear motor or voice coil.
  • The Solo Guitar can operate as a stand-alone device or as part of a multi-axis system in a distributed configuration on a real-time network.
  • The Solo Guitar is equipped with four powerful digital outputs. It is designed to deliver up to 250 mA in each output when it is defined as general purpose applications or up to 500 mA when it is defined for braking applications.
  • The Solo Guitar provides two differential ports for Auxiliary feedback. The relevant functionality of Feedback B port is configured via the user interface.
  • The Solo Guitar provides an input for thermal motor protection. Digital input 1 is allocated for that purpose.
  • The Solo Guitar provides a "main differential buffered output" (not available for the Solo Guitar absolute feedback model ).
  • The Solo Guitar drive is easy to set up and tune with Elmo’s Composer software tools.
  • This Windows-based application enables users to quickly and simply configure the servo drive for optimal use with their motor.
  • The Solo Guitar, as part of the SimplIQ product line, is fully programmable with the Elmo Metronome motion control language.
  • The Solo Guitar delivers up to 4.8 kW of continuous power or 5.4 kW of peak power, package (46.7 x 61 x 80 mm or 1.84" x 2.4" x 3.15").
  • The Solo Guitar uses a 12 ~ 195 VDC isolated DC power source (not included with the Solo Guitar).
  • A “smart” control-supply algorithm enables the Solo Guitar to operate with only one power supply, with no need for an auxiliary power supply for the logic.
  • To back up and store control parameters in the event of a power outage, an external 12 ~ 195 VDC isolated supply can be connected to the Solo Guitar to maintain maximum flexibility and backup functionality when needed.
