Troubleshooting; Specifications - Geckodrive G203V Installation Notes

MAIN CONNECTOR: The G203V uses a 2-piece modular main connector. The connector is split in two pieces;
terminals 1 thru 6 (power supply and motor leads) and terminals 7 thru 12 (control interface). Each can be removed
separately by pulling the connector body upwards and off of the mating header pins on the G203V. The connectors
must initially be removed to mount the G203V to a heatsink or chassis.

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. Those
are reversed power supply polarity; AC voltage instead of DC voltage on terminals 1,2 and power supply voltages
in excess of 114VDC. Correct the problem and replace the fuse with the only approved type. It is the only kind that
blows fast enough to protect the G203V. Anything else voids the warranty.
EVERYTHING IS CONNECTED, RED INDICATOR STAYS LIT: If the RED and GREEN indicator LEDs are lit then
the motor is miss-wired, the motor has a wire shorted to ground, is shorted to another motor wire or the motor is
bad. Secondarily: Everything ran OK but the RED LED lit a while later. Check the drive temperature; it may have
overheated because of inadequate heatsinking. Also see that the DISABLE input isn't being activated (+5VDC on
DISABLE).
MOTOR HAS NO HOLDING TORQUE: If the RED LED is off and the GREEN LED is on, check the CURRENT
SET resistor with a multimeter. Re-calculate the resistor value. Check to see if the motor is connected to the
G203V.
MOTOR HAS HOLDING TORQUE BUT WON'T MOVE: Check your STEP, DIRECTION, DISABLE (if used) and
COMMON interface. Verify COMMON goes to your controller GND.
MY MOTOR RUNS ROUGH AT LOW SPEEDs: Try adjusting the ADJUST trimpot setting. Verify you are using the
correct CURRENT SET resistor. If you are using a 'round' motor, it won't be as good as a 'square' motor.
MY YELLOW LED NEVER LIGHTS: You are not going fast enough to get full power from your motor. If you don't
need to go any faster, use a lower power supply voltage. This indicator is a good application diagnostic for motor
gearing and power supply voltage choice. Using it correctly will help you to optimize your system.
