TECHNICAL DATASHEET Astrosyn Astrosyn International Technology Ltd The Old Courthouse, New Rd Ave, Chatham, Kent ME4 6BE, England Tel: +44(0)1634 815175 Fax: +44(0)1634 826552 www.astrosyn.com 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 Additional Specifications Drive current: Adjustable from 2.8A to 8.5A Supply voltage: Input voltage from +24V to 110Vdc Step control: Full step or microstepping Control inputs: Connections for pulse, direction and enable signals Pulse signal: Speed control to maximum frequency 200kHz Direction signal: Clockwise or counter-clockwise rotation Enable signal: Driver enable or disable Logic signals: Current from 6mA to 30mA Material: Black coated aluminium with integral heatsink Mounting: Free standing or via mounting holes Dimensions (WxHxD): 97.5x 150 x 53 mm Mass: 600g
