• Microstepping will reduce noise levels and can increase positional accuracy by a large amount.
• Control input via serial port, TTL or RS-232 levels, 2400 or 9600 baud.
• Computer can also query controller for motor position and current draw.
• Up to two stepper motors may be independently controlled at one time.
• Each motor may be either 4-pole Unipolar or 2-pole Bipolar.
• Each motor may draw up to 1.0 amps per winding.
• Outputs can be bridged to handle a single motor with up to 2 amps/winding.
• External cooling required for 0.5 amp motors or larger.
• Rates of 1 to 62,500 microsteps per second are supported
• Automatic linear ramping of step rates; independently programmed for each motor; 1 to 62,500 microsteps per second per second.
• Motor coordinates are maintained as 32 bit signed values, and thus have a range of –2,147,483,647 through +2,147,483,647.
• TTL "busy" signal indicates when the motors are moving.
