1. Family Overview
Introduction
The iSS57 series integrated stepper servo includes a NEMA23 stepper motor with internal encoder and drive board.
Compared with traditional discrete motor and drive, its compact size saves the mounting space of the machine and
reduces setup time during the assembling process. Its drive board adopts Leadshine’s latest hybrid servo control
technology, offering high staring torque, smooth motion and super-low motor noise at low speed. Its output current is
dynamically controlled depending on the load condition thus greatly reducing the motor heating. Its internal encoder
offers actual motor shaft position information and eliminates the possibility of losing steps. In addition, it can output
the in-position and alarm signal like servos for complete system control.
The iSS57 offers an alternative for applications requiring high performance and compact size. Its great feature of fast
response and no hunting make it ideal for applications such as bonding and vision systems in which rapid motions
with a short distance are required and hunting would be a problem. And it is ideal for applications where the
equipment uses a belt-drive mechanism or otherwise has low rigidity and you don't want it to vibrate when stopping.
