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
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.
