HIGH PERFORMANCE MICROSTEPPING DRIVER

MODEL P860

Model P860 is a fully digital high performance DSP driver suitable for 2-phase and 4-phase hybrid steppers

requiring a drive current of up to 8.5A/phase. The design features an advanced bipolar constant-current

chopper circuit with current control technology. This driver is suited to stepper motor control applications

requiring low noise, low vibration, high speed and high precision.

 High performance at a low cost

 Supply voltage 24V to 110V dc, current to 8.5A

 Current selectable from 2.8A to 8.5A / phase

 Inaudible chopping frequency

 TTL compatible and Optically isolated input signals

 Automatic idle current reduction

 Mixed-decay current control for reduced motor heating

 16 selectable step resolutions in decimal and binary

 Microstepping to 51200 steps/revolution

 Suitable for 4, 6 or 8 lead wire motors

 Step,Direction and Enable inputs

 Over temperature and over voltage protected

 Short circuit protected
