Series G9003

G9003 is the 1-axis programmable pulse generator used as a local device for the Motionnet high-speed serial communications system.
Various functions include overriding prevailing pulse rate and target position, elimination of triangular drive, backlach correction, suppression of vibration at cessation, programmed limit, diversified origin return sequences, inputting mechanical signals, and servomotor interface. These abundant functions enable the user to easily configure any complicated motion control system.
The status of general-purpose input/output ports and axis control information are cyclically communicated to/from the center device. Axis control commands and register parameters are the chip is mounted to motionnet boards.


  • By connecting 64 units of G9003 to the line
  • Interrupt signal output and external output of comparison results
  • Immediate stop or deceleration-stop
  • Programmed limit
  • Out-of-step detection
  • Synchronization signal output
  • Number of general-purpose input/output ports : 1(8 bits); input or output can be defined for each bit.
  • Communication data length : 1 to 4 words/ frame (1 word = 16 bits)
  • Communication mode : Cyclic for I/O port and transient for parameter transfer
  • Pulse output mode : Selectable from 12 types of pulse signal output and 2-phase stepping motor excitation sequence
  • 12 major operation modes
  • Manual pulse input terminal with functions to multiply by 32 and to divide by2048
  • 14 types of error factors and 13 types of event factors are available to initiate and interrupt signal (event factor can be selected by the register)
