Integrated Dual Whistle Solution
The power of 2 Whistle servo drives in a single solution |
| Elmo's Duo is an integrated solution for X, Y applications. Highly
compact, it combines two Whistle
servo drives Controller in one package and operates using a single DC power supply. The Duo is offered as two
different models supporting either 60 or 100 maximum DC voltage with a continuous current of up to 15
amps. |
| The Duo operates from a DC power source in current, velocity, position
and advanced position modes with permanent-magnet synchronous brushless motors, DC brush motors, linear
motors or voice coils. The solution is designed for use with any type of sinusoidal and trapezoidal
commutation with vector control. |
| As with other Elmo SimplIQ
digital products, the Duo can be easily
set up and tuned using Elmo's Composer
software tools. |
