The current must be set to a level such that the energy delivered can be absorbed by the load, excess current can excite resonances.For heavy-duty and precision applications, try our Precision Joystick which does not have a detent in the center and is much easier to control at very low velocities.Typically use shielded twisted pairs to reduce noise and connect shields to ground. Do not bundle motor wires with limit wires as the noise from the motor wires may cause false trips on the limits.20K ohm pullup to 5V is included on the board on each limit input. The internal 1K ohm resistor can be shorted across for direct access to the 5V supply if desired, however, the total current must be less than 20mA total for all 4 sensors. The supply to the opto LED is limited to 4mA per LED by a series 1K resistor on the board.This ensure that any disconnect of the limit will “fail safe”
Limit inputs expect to be low for normal motion.Motors that are size NEMA 23/17 or smaller are a good match for this drive. Suitable for XY Stages or Pan-tilt mechanisms.
Max speed 5800 steps per second (1740 rpm) for a 1.8 degree per step motor.Motor rated current: 0.05A – 5A (motors rated at > 2A will output less than max torque).Motor rated voltage: 1V – 90V (for best high speed performance, use a motor rated at 1/4 of supply voltage, e.g.Current to motor: 0.05A – 1A max / 0.05A-2A max.Push button Turbo mode for high speed modes.Automatic motor current reduction to 25% of set value when not moving.Motor acceleration is set via trimmer potentiometer.Motor max velocity is set via trimmer potentiometer.
