POWER SUPPLY HOOKUP
TERMINAL 1
Power Ground
Connect the power supply ground to term.1
TERMINAL 2
Power (+)
Connect the power supply “+” to this terminal
The power supply voltage must be between 18 VDC and 80 VDC. 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. The drive has a 2 second power-on reset time before the motor is energized.
CAUTION! Power supply voltage in excess of 80 VDC will damage the G201X.
CAUTION! Never put a switch on the DC side of the power supply! This will damage, if not destroy, your drive!
The choice of power supply voltage depends on the high speed performance required of the motor; doubling the voltage doubles
the motor’s high speed power. In all cases the power supply voltage should be no less than 4 times or no more than 25 times the
motor’s rated voltage. The motor may not run as smoothly as possible if the power supply voltage is less than 4 times the motor’s
rated voltage. A power supply voltage greater than 25 times the motor’s rated voltage will overheat and damage the motor, even
if it is not turning. Motor winding inductance should be 500uH or greater, but generally no more than 7mH.
A more accurate calculation of power supply voltage is to find your motor’s inductance, and put it into the following equation.
32 * (√mH inductance) = Power Supply Voltage
If your motor has 2mH of inductance, the equation would look as follows.
32 * (√2) = 45.12V
MOTOR CONNECTION
TERMINAL 3
Phase A
Connect one motor winding to this terminal
TERMINAL 4
Phase /A
Connect the other end of the winding to this terminal
TERMINAL 5
Phase B
Connect the other motor winding to this terminal
TERMINAL 6
Phase /B
Connect the other end of the winding to this terminal
Connect one motor winding to terminals 3 and 4. Connect the other winding to terminals 5 and 6. Turn the power supply off
when connecting or disconnecting the motor. If the motor turns in the wrong direction, reverse the motor winding connections
to terminals 3 and 4.
CAUTION! Do not short the motor leads to each other or to ground; damage will result to the G201X.
4-wire, 6-wire and 8-wire motor 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. The choice depends on the high-speed performance
required; a parallel-connected motor will provide twice the power of a series-connected motor at the same power supply voltage.
