No matter what load condition is and how much current is needed, the flex3 sample chapter 23 pdf stepper driver will always output a constant current.
Main Features tab to read more information.It is a great feature of the iES when rapid motions with a short distance are required and it is ideal for applications such as bonding and vision systems in iso mounting software daemon which hunting would be a problem.The drive can then fully close the position loop, which is the same mechanism as classic brushless servo drives.Since the iES easy servo is a stepper motor based system, it operates in synchronism with command pulses and has no hunting problem.Please click the above.Our Supply Network : Andhra Pradesh, Arunachal Pradesh, Guwahati, Assam, Sikkim, Nagaland, Mizoram, Gandhinagar, Kanpur, Varanasi, Patna, Agartala, Karnataka, Bhubaneswar, Assam, Hyderabad, Bhopal, Indore, Dehradun, Rajasthan, Lucknow, Punjab, Kerala, Moradabad, Mumbai, New Delhi, Ludhiana, Jaipur, Chandigarh, Pune, Rudrapur, Tamil Nadu, Goa, Tripura, Bangalore, Chennai, Orissa.In addition, the totally integrated design minimizes wiring cables, saves mounting space, and is more reliable to external interference.Motor heat is 20 to 40 oC lower compare to a conventional stepper drive which runs at full current most of the time.
If necessary, the iES drives will compensate the loss of synchronization, which is usually caused by abrupt load fluctuations or accelerations, and can not be compensated with a conventional stepper.
Since the iES runs in closed-loop, the iES drives only put as much current into the motor as required to drive the motor to the target.
A Leadshine integrated closed loop stepper motor consists of a high torque stepper motor, a rotary encoder, and an integrated DSP-based digital easy servo drive.This feature significantly improves system high speed performance.To suit your specific application, Thomson offers the longest stroke lengths in the industry, a simple and reliable RediMount system to mount your own motor, and product customization options.Their unique features make them ideal solutions especially for applications requiring low costs, high torque, quick response acceleration, quick settling time, closed loop control, small installation space, such as electronic dispensing machines, semiconductor equipments, CMM measuring, medical devices, high performance CNC routers / mills.Leadshine integrated closed loop stepper motors inherit the favored features of both open loop stepper and brushless servo systems.Smooth motion and extra low motor noise Click to Enlarge, unlike a conventional stepper drive, the iES easy servo drives adopt vector control and filtering, producing a smooth motion with minimum torque ripples.When it stops, its position is completely stable and does not fluctuate.Set the microstep resolution and operating current, then the system is ready and offers high performance approaching to a fine tuned servo.An iES integrated easy servo has an easy servo motor and an easy servo drive.Our Export Network : Afghanistan, Bahrain, Bangladesh, Bhutan, Canada, Boston, Egypt, Cairo, lagos, Ikeja, Dubai, Uae, Sharjah, Abu Dhabi, Sudan, Dhaka, Bangladesh, Nepal, Bhutan, Sri Lanka, Ghana, Israel, Kenya, Lebanon, Malaysia, Mozambique, Oman, Namibia, Nepal, Nigeria, Qatar, Russia, Singapore, Saudi Arabia, Dammam, Kuala Lumpur, Indonesia.No torque resovation for broader operating range Click to Enlarge.Embedding Sensors and Motors will introduce you to the design of sensors and motors, and to methods that integrate them into embedded systems used in consumer and industrial products.

PC Series Webinar Recording: Replace Pneumatics with Electric Actuators.
Plug and play, no tuning for most of applications  Click to Enlarge, unlike a servo system which usually needs the engineer to spend a long time to learn how to use tuning tools and tune the gains for a satisfying  performance, the iES series .
Therefore, loss of movement synchronization (step loss) in open loop stepper systems is totally eliminated.
