Press the NEEDLE UP / DOWN button, the program will go
back to the operation mode.
Start again.
If the machine operates normal:
1.
Check the motor plugs for proper connection
2.
Check the temperature of the motor.
3.
If the motor turns too hot, check the mech. part of the
machine
4.
Run the test for the balance of the motor.
If the machine turns about one revolution with uncontrolled speed:
The encoder pulses are missing.
1 Check the encoder plug for proper connection.
2.
Run the encoder test
If the machine does not run at all:
1.
Check all motor plugs for proper connection
2.
Check your line voltage (must have at least 180 volt).
3.
Remove the motor and run the motor test.
4.
Check the overload LED (red LED at the front of the control
box).
If the LED is lit, turn the power off and wait at least one minute.
Turn the power back on.
If the machine runs normal, a spike may have caused the
problem.
CHECK FOR PROPER GROUNDING.
