POSSIBLE CAUSE
POSSIBLE SOLUTIONS
-
The EN terminal (Enable Outputs) is
not enabled.
The board requires to be
externally enabled.
-
Make sure you are providing +5vdc to
the EN terminal. This +5vdc can be
taken from the terminal next to it.
-
The Safety Charge Pump is not
configured.
The Safety Charge Pump
can either be configured in the control
software or disabled by moving the
jumper to the disable position.
-
Start by disabling the SCHP. Enable it

setup.
-
The parallel cable is not well
connected to the PC parallel port.
-
Check if the parallel port is well
connected to the PC.
SYMPTOM 3:
THERE IS NOISE IN THE SYSTEM, OR THE MOTORS DO NOT
MOVE SMOOTHLY.
POSSIBLE CAUSE
POSSIBLE SOLUTIONS
-
The board could be underpowered.
-
Make sure you are using a +5vdc
400mA power supply.
-
There could be a short that could be
draining the power to the board.
-
Check that there are no hot spots in the
board or it’s connections.
-
Measure
the
board’s
power
consumption, it should be less than
400mA (depending on the features
used).
-
Blown chips could create an internal
short and end up drawing power that can
affect how other chips work.
-
There could be an external noise
source that could be introducing
noise into the system.
- Try using shielded cables.
- Try to isolate VFDs or AC servos, etc.
- Try using 103. 0.1mF caps between the
I/O terminal and a ground of the board.
SYMPTOM 4:
A I/O PIN MIGHT NOT BE WORKING.
