1 Introduction
This manual contains information required to configure over an USB and run the PoStep60 driver.
Please read the manual carefully to avoid damage to the driver. This section covers the instrument
general description, instrument specifications and characteristics.
1.1 General symbols for this instructions
A few symbols are used throughout this manual that you should be aware of in order to complete
certain tasks safely and completely. These symbols have different degrees of importance as
described below:
2 Description
The PoStep60 driver incorporate advanced stepper motor controller and external N-channel
MOSFETs to drive a bipolar stepper motor or two brushed DC motors. A micro-stepping indexer is
integrated, which is capable of step modes from full step to 1/256-step. An ultra-smooth motion
profile can be achieved using adaptive blanking time and various current decay modes, including an
auto-mixed decay mode. A simple step/direction or PWM interface allows easy interfacing to
controller circuits. An I2C serial interface can further be used to control all the driver functions
including position control on board. All running parameters (output current (torque), micro stepping,
step mode, decay mode...) can be set over USB and stored on board for standalone operation.
Internal shutdown functions are provided for over current protection, short circuit protection, under
voltage lockout and over temperature. Fault conditions are indicated via a FAULT LED, and each fault
condition can be read in configuration software.
