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 Model P403A Stepper Motor Driver General Specification Model P403A is a high performance microstepping driver suitable for 2-phase and 4-phase hybrid steppers requiring a drive current of up to 3.5A / 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. Key Features  Supply voltage to +40Vdc, current to 3.5A  Inaudible 20khz chopping frequency  TTL compatible and optically isolated input signals  Automatic idle current reduction  Mixed-decay current control for reduced motor heating  15 selectable step resolutions in decimal and binary  Microstepping to 51,200 steps/revolution  Suitable for 4, 6 or 8 lead wire motors  Overcurrent and overvoltage protected  Short circuit protected  Compact size Additional Specifications Drive Current: Adjustable from 1.3A to 3.5A Supply Voltage: Input voltage from +24V to +40Vdc Step Control: Full step, half step or microstepping Control Inputs: Connections for pulse, direction and enable signals Pulse Signal: Speed control to maximum frequency 200 kHz 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): 45 x 132 x 76 mm Mass: 360g
