Product Overview

The 4 71 748 980 evaluation kit is a complete electronic controller for unipolar and bipolar stepper motors. The core contains an efficient 8bit microcontroller MC68HC908GP32 with 32Kbyte EPROM as program memory. Thus it is ensured that in the test phase program modifications and new parameter settings can be done easily. The microcontroller is equipped with the modules ADC, UART, SPI interface, two timers for step generation/process control and many I/O ports. On the board, integrated stepper motor drivers permit both the direct porting of four coil unipolar stepper motors and two coil bipolar stepper motors. Bipolar stepper motors can be used in the constant current mode, the height of chopper current can be adjusted. It is possible to control the bipolar stepper motors by micro stepping. Digital inputs and outputs as well as an analog input permit the integration of the evaluation kit into complex drives or customer applications. LEDs indicate the operating conditions.
  • With 32Kbyte flash EPROM and internal periphery
  • Supply of regulated supply voltage for logic components
  • Stepper motor driver with power output stages (2 two separate H bridges)
  • Control of two coils of a bipolar stepper motor
  • Selectable Zener diodes for fast decay of motor current
  • Serial RS485 interface for programming and operation control of the evaluation kit in a network
  • Potentiometer for position control in the 0V to 10V mode
  • Two digital control signals used in the PLC mode
  • Four open collector outputs for control functions and indication
  • Three LEDs to indicate operating conditions, available in PLC mode
