1. Family Overview
Introduction
Leadshine
’
s IES integrated easy servo motor is a stepper motor integrated with a 1,000-line (4,000 PPR) encoder and
a hybrid servo drive. At very compact size and with all components integrated, the IES can save mounting space,
eliminate encoder connection & motor wiring time, reduce interference, and cut/reduce cable and labor costs.
By adopting Leadshine
’
s latest hybrid servo control technology, the hybrid servo drive of the IES can drive the
stepper motor with high staring torque, high precision, smooth movement, and extra low noise at low speed
movement with no obvious resonance area. Different from constant-output-current output from a drive to a stepper
motor in normal open-loop stepper controls, output current of the IES is dynamic and changes depending on load
condition, same as servo controls. Therefore, it can significantly reduce motor heating and increase motor lifetime.
The drive takes step & direction input commands, and is capable of outputting in-position and fault signals back to a
motion controller or external devices, for complete system controls.
The integrated 1,000-line encoder of can offer the real-time motor shaft position to the drive. Based on that position,
the drive can then close the loop between the motor and drive, ensure no step is lost, and eliminate the possibility of
stall or loss of movement synchronization which is often found in open-loop stepper systems. By getting rid of
torque reservation in open-loop stepper systems, the IES can significantly improve high speed performance by as
much as 30%. In addition, the IES performs much better in response time and speed acceleration over open-loop step
systems.
Compared with brushless servo systems, the IES has much higher low speed torque, no overshooting & zero settling
time, no overshooting, no hunting, and no/little tuning. Significant cost cutting also makes the IES ideal for the
motion control systems in many applications.
Applications
Leadshine
’
s IES integrated easy servo motor offers an alternative solution to fill the gap between budget open-loop
stepper systems, and expensive high performance brushless servo systems. It combines the features of high
low-speed torque of open loop stepper, and closed-loop movements of traditional servo systems. Integration design
with motor, drive, and encoder significantly reduces setup time and cut costs of your control systems.
Advanced features over open-loop stepper systems, such as much higher high-speed torque, no loss of movement
synchronization, much lower motor heating, no obvious resonance area, etc., make the IES ideal product for
upgrading stepper systems to get performance boost for many stepper applications such as CNC routers, CNC laser
cutting machines, CNC milling machines, CNC lathes, medical / biotech equipments, lab automation instruments,
etc.
Features over traditional brushless servo systems, such as significant lower costs, no hunting, no overshooting, easy
setup, etc., make the IES ideal products in many traditional servo applications such as short distance movement
boding type machines and vision applications. Its natural feature of high low-speed torque makes the IES a perfect
product for replacing many high-cost servo applications with gear head speed reduction.
