Introduction
Fully digital AC servo drive ACS806 is developed with 32-bit DSP based on advanced control algorithm. Since its input commands are PUL/DIR signals, the users can upgrade stepping drives to the ACS806 without changing control systems. The ACS806 can offer high precision, high speed and high reliability performance, and widely used in inkjet printers, engraving machines, and etc. A built-in controller can be used for testing and tuning. PC based and handheld configuration & tuning tools can meet different tuning environments or requirements.

Signal
|
Description
|
|
ENA+/ENA-
|
Enable input signal. This signal used for enabling/disabling the drive. High level for enabling the drive and low level for disabling the drive. Usually left UNCONNECTED (ENABLED).
|
|
PUL+/PUL-
|
Pulse input signal. In single pulse (pulse/direction) mode, this input represents pulse signal, each rising or falling edge active (software configurable); 4-5V when PUL-HIGH, 0-0.5V when PUL-LOW. In double pulse mode (pulse/pulse) , this input represents clockwise (CW) pulse,active at both high level and low level . For reliable response, pulse width should be longer than 0.85µs. Series connect resistors for current-limiting when +12V or +24V used. The same as DIR and ENA signals.
|
|
DIR+/DIR-
|
Directions input signal. In single-pulse mode, this signal has low/high voltage levels, representing two directions of motor rotation; in double-pulse mode (software configurable), this signal is counter-clock (CCW) pulse,active at both high level and low level. For reliable motion response, DIR signal should
