Microstepping Driver R364

photo
  • 3-axis step motor controller and driver PCB
  • Phase currents between 0.2 to 1.5 Amps/Phase (Software Programmable)
  • Software selectable step resolutions from Full step, Half step, and 4x, 8x, 16x, 32x, 64x microstepping operating.
  • On-board control interfaces are provided for both RS232, for single module control and RS485 for multiple module control.
  • Operating at 57,600 baud the coordinated control of up to twelve axes is practical using four R364 PCB modules on a common RS485 bus.
  • Up to 15.6kHz of step frequency
  • Left and Right limit switch inputs for all motors Home reference by commanded automatic sequence for each motor. The Left Limit Switch is found. The motor then moves to a user given offset position, and then sets the current position to be zero.
  • Eight inputs 0 to 5 VDC analog, or eight inputs TTL digital
  • Seven open-collector relay or solenoid drivers, and one TTL output

Connecting Multiple R364 Boards

Multiple R364 modules can be controlled from a single computer port. Each module is assigned a unique address character, and the RS485 bus ports are wired in parallel. Unless you have a RS485 I/O card in your computer you will need the RS485 to RS232 Converter Card (ACC-01, sold separately) to control the multiple R364 boards using your PC serial port. (See Section 11 in the manual)
NOTE: RS485 to RS232 Converter Card is not necessary for single board connections. A single R364 board can connect using the onboard RS232 or RS485 connectors.
