CHAPTER 8
TROUBLESHOOTING
8.1 GECKO DRIVER (G203V
)
•
If the GREEN LED is not lit, either the G203 has no power supply voltage connected or something
very bad caused its internal fuse to blow. Check the power supply voltage using s multi meter
set to “DC VOLTS” on terminal screw he
ads 1, 2 of the drive.
•
If the RED and GREEN indicator led 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, if
everything ran ok but the RED LED lit a while later. Check the drive temperature; it may have
overheated because of inadequate heat sinking. Also see that the disable
isn’t being activated.
•
If the motor has no holding torque and the RED LED is off while the GREEN LED is on, check the
CURRENT SET resistor with a multi meter. Re-calculate the resistor value. Check to see if the
motor is connected to the G203V.
•
If the 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.
•
If the motor runs rough at low speed, try adjusting the ADJUST trim pot 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.
•
If the YELLOW LED never lights, you are not going fast enough to get full power from your
motor. If you don’t need to go 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.
8.2 BREAK OUT BOARD (C11G
)
•
If the output and input led are not lit, check the wiring connections, you only have to screw on
the wires to make all the connection tight.
•
The board re5vdc in the EN pin. If it is not present, it will send all the outputs to ground.
You can use this to enable or disable the system manually, or you can install an external safety
charge pump or other external devices.
•
This card can be used to opto isolate any existing set up just by connecting this card between
the computer and current control box. That way, you can also see and access all the signals.
