Features
■Small size
3cm x 6 cm x 1.5 cm (CB/CF Type)
■Micro-stepping
Programmable 1/16 – 1/32 micro step interpolation
(1/4 – 1/8 version also available on request)
■Less no. wires
Built-in 115200 baud rate serial Interface (RS485)
to communicate up to 32 axes.
One-wire serial interface for status monitoring
■Cost saving
Motion profile generator with smart homing is implemented. Motion card is not necessary.
■Flexible I/O’s
Multiple function digital inputs (CW/CCW, position indexer, Positive/Negative limit senor inputs JOG…)
■Easy wiring
Two versions of extension boards, isolation (ID)
and non-isolation (ND) are available.
