Description
The NGD80 is an ultra-compact driver for 4-phase stepper motors programmable with LADDER language and speed synchronism linked to 0-10V analog signal or encoder. The driver also features 12 I / O points, two adjustable analog references, a USB port and a half-duplex RS485 programming and debugging socket and software filters for digital and analog inputs
