Thank you for purchasing the G203V drive. The G203V is Geckodrive’s new generation CPLD-based microstep drive. It has shortcircuit protection for the motor outputs, over-voltage and under-voltage protection, over-temperature protection, reversed power supply polarity protection and will survive accidental motor disconnects while powered-up. The G203V uses a synchronous PWM design that is absolutely silent when the motor is stopped or turning slowly.
TERMINAL 10 Common Connect the controller’s GROUND to this terminal. TERMINAL 11 Current Set Connect one end of your current set resistor to this terminal. 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.
CAUTION! Avoid shorting the motor leads to each other or to ground or the G203V will enter protective shut-down. 4-wire, 6-wire and 8-wire motor may be used. If 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.
OTHER CONSIDERATIONS: HEATSINKING: The G203V needs heatsinking for current settings greater than 3 amps. The case temperature (measured on the bottom plate) should not exceed 70 degrees C, and for best life should be kept at 50C degrees or less. Use heatsink compound between the G203V and your heatsink. CAUTION! Current settings above 3A without a heatsink may result in the G203V entering thermal shutdown.
TROUBLESHOOTING: EVERYTHING IS CONNECTED, NOTHING HAPPENS: Is the GREEN LED lit? If not, either the G203V has no power supply voltage connected or something very bad caused its internal fuse to blow. Check the power supply voltage using a multimeter set to ‘DC VOLTS’ on terminal screw heads 1,2 of the drive. The internal fuse is the G203V’s final line of protection. It blows only under the most extreme circumstances.
This section applies only if you purchased a G213V or have installed a G901X step pulse multiplier. A G203V without a step pulse multiplier has a fixed 10 microstep resolution. ADJUSTING MICROSTEP RESOLUTION The G213V has an onboard step pulse multiplier called the G901X that allows the drive to operate in full step, half step, 5 microstep and 10 microstep modes. The G901X uses a 2mm jumper block and two jumpers to set the resolution.
