General description ;

1) 3 methods of control :
1-1) open loop
1-2) close loop with incremental rotary encoder feedback
1-3) close loop with incremental linear encoder feedback
2) 2 MODES of operation ( RUN mode and PROGRAM mode )
3) control of start / stop from keypad or external contacts ( Terminal )
3) 3 memory for saving the destination of movement ( 0.01 mm resolution )
4) easy to change the destination point by keypad while running or stop
5) linear ramp for acceleration & deceleration of movement
6) start speed , maximum speed and scale easily set for each memory
7) absolute or incremental mode selection
8) backlash compensation capability
9) 1x or 4x multiplier for feedback pulses from encoder
10) keypad lock / unlock for safety of parameters
11) 50 kHz maximum pulse output frequency
12) 50 kHz maximum feedback frequency from encoder accepted
13) 6 digit LED 7-segment display for each memory (target position) and current position
14) auxiliary output (+5V , +12V @ 300mA each) for external use
15) 220 VAC , single phase input supply voltage
