1. Introduction, Features and Applications
Introduction
The DCS810S is a digital DC servo driver developed with DSP and high efficient
MOSFET technologies. In position control, it’s easy for the end users to change
stepping drivers to the DCS810S without changing control systems, because its
input command is PUL/DIR signal, which is compatible with that of stepping
drivers. In low power motion control applications, performances of DC servo
systems using the DCS810S are better than those of digital AC servo systems in
velocity, precision, stability, or at least as good as those of digital AC servo systems.
However, the cost of the DCS810S stays at the price line of stepping driver, namely
far lower than those of AC servo drivers.
Compared to the DCS810, the DCS810S accepts single-ended encoder signals while
the DCS810 accepts differential encoder signals.
The DCS810S is very easy to tune and all parameters are visible. PC based and
handheld configuration & tuning tools, including Pro Tuner (Windows based setup
software) and STU (Small servo tuning unit) can meet different tuning environments
or requirements.
