TERMINAL 12
Current Set
Connect the other end of your current set resistor to this terminal.
POWER SUPPLY WIRING
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 15 VDC and 80 VDC. The maximum power supply current required is equal to the
motor’s rated phase current. An unregulated power supply may be used so long as the voltage stays between the specified limits;
keep the power supply ripple voltage to 10% or less for best results.
CAUTION! Power supply voltage in excess of 80 VDC will blow the G203V internal fuse.
CAUTION! Reversed power supply polarity will blow the G203V internal fuse.
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 required high-speed performance from 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 20
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
or more than 20 times the motor’s rated voltage. A power supply voltage greater than 20 times the motor’s rated voltage may
overheat and damage the motor. Motor winding inductance should be 500uH or greater.
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
One motor winding connects to terminals 3 and 4 and the other winding connects 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.
