G251X MANUAL STEP MOTOR DRIVE
Thank you for purchasing the G251 drive. The G251 microstep drive is warranted to be free of manufacturing defects for 3 years from the date of purchase. Anyone who is dissatisfied with it or is unable to make it work will be refunded the purchase price if the G251 is returned within 90 days of the purchase date and is in like-new condition. PLEASE READ FIRST BEFORE USING THE G251 Before beginning, be sure to have a suitable step motor, a DC power supply suitable for the motor and a current set resistor.
POWER SUPPLY CONNECTION TERMINAL 1 Power Ground Connect the power supply ground to this terminal TERMINAL 2 Power (+) Connect the power supply “+” to this terminal The power supply voltage must be between 15VDC and 50VDC. The maximum power supply current required is 67% of the motor’s rated phase current. An unregulated power supply may be used as long as the voltage stays between the limits; keep the ripple voltage to 10% or less for best results.
CAUTION! Do not short the motor leads to each other or to ground; damage will result to the G251. 4-wire, 6-wire and 8-wire motors may be used. When 6-wire motors are used, they may be connected in half winding or full winding. This is equivalent to an 8-wire motor connected in parallel or series. If a motor is connected in series or full winding, the motor’s phase current rating is half of its parallel or unipolar rating.
