Microstepping drivers 20V…240V 0.8Arms…10Arms for two phase stepper motors

High reliability and performance, compact size and low cost are the main characteristics of the drivers of the OS10xx series. Realized in open design they can be easily integrated inside equipments and cabinet. The driver is mountable through 4 holes, suitable for M3 screws, placed on the corners of the board. The connection to the motor, with the logical signals and to the power supply is through three different terminal blocks, each one of them is numbered and suitable for 2.5mm Decimal and binary resolution Resolution up to 25.600 step/rev STEP frequency over 300KHz Wide range of power supply High current density Resonance damping Automatic current reduction Accurate current control
2 Chopper frequency over 20KHz wire size. Using the last electronic components generation and the SMT technology it has been possible to obtain in a small space high power and advanced performances. The many setting options available allow to use the drivers with any kind of motor and application. The phase motor current can be tuned fine in a wide range of value as the step resolution, the current reduction, etc. Each logic signal can be set independently from the other to PNP or NPN logic, each input can also be driven using line-driver technology. The driver is fully protected to preserve its integrity from the most common problems. The diagnostics is complete and univocally signals whenever one or more protections occur. Furthermore a break motor phase diagnostics is also available, very useful to determine wiring problems or motor failures. The complete setting of the driver is immediate and simple thanks to the graphic software designed for Windows platform. High efficiency power mosfet stage Optocoupled and differential I/O, independently NPN or PNP usable Inputs working from 3Vdc up to 30Vdc with constant current Line driving supported Digital signal conditioning for each I/Complete diagnostics with unO ivocalionuit protection ns on screw terminal block indication for each anomaly Over/under voltage protection Cross phase short circuit protect Ground short circuit protection Positive supply short circ Overheating protection Break motor phase diagnostics Compact size Connectio Low cost The connection to the programming DUP port of the driver is possible through the UDP30 inte rface, which is connected to the PC by the USB port.
