Anyone who has ever had to control a motor knows how much work goes into developing the correct hardware and software. They’ve experienced firsthand the almost endless amount of time it takes to realize even simple movement patterns with acceleration and deceleration ramps.
The industry offers a few approaches to reduce this work load, but sadly most of these still require a very specific and time intense configuration. Complex protocols, industrial interfaces with external interface converters, driver installation or getting to know the SPS development environment of a specific supplier often make the fast or easy operation of a motor impossible.
The time savings achieved by eliminating device drivers and configuration programs streamlines application development substantially. Especially in the field of research and development, or in an educational environment, application development time can be noticeably reduced. The only thing required for motor configuration is a web browser. Whether you decide to use a PC, a tablet or even a smartphone; if it has a web browser, you can control the HDrive! Set two positions – Assign them to two buttons – Done!
Unlike current servo drives Henschel Robotics doesn’t force you to use complicated and cumbersome control sequences to control movement. One simple and understandable command is all it takes to move an HDrive:
<system position=202 speed=10 torque=10 mode=2>
This command sets the motors new target position to 20.2°. Many programming languages enable sending such text commands with just a few lines of code. This easy to use interface makes programming even complex movement patterns a breeze.
Comfortable PC Control
Ethernet based control makes the motor efficient and reliable. Prototypes and functional models can be controlled directly from a PC. SPS configuration or driver development, which can easily take weeks of development time, fall away completely!
For time critical applications, the HDrive additionally offers a Step/Dir as well as a CAN-Bus interface.
The HDrive has an internal motion planner, which continually recalculates the required motor states, and reacts to any disturbances. The motor calculates the required acceleration and deceleration ramps required to reach a target position by itself.
Position control performance
Similar to how a BLDC motor works, our stepper motor relies on field oriented control. This essentially makes the stepper motor behave much like a many-poled DC motor. The stepper motor no longer uses “steps” and REACTIVE and ACTIVE CURRENT can be controlled independently. This enables a continuous motor torque. Under lab conditions speeds of over 10’000 RPM have been reached. Additionally, the steppers motors used in the HDrive are very robust and reliable.
