TROUBLE SHOOTING
The control box of the Super Midi Miller will show fault codes according to different problems which the
machine may encounter during use.
Please check from the list below the most common fault codes of the
Super Midi Miller control box. If a code other than those shown below is received, or if the fault does not
correct, please write down the error code and contact your reseller.

1
Output over current
Instantaneous over current on the drive output. Excess load or shock load on the motor.
Note: Following a trip, the drive cannot be immediately reset. A delay time is inbuilt, which
allows the power components of the drive time to recover to avoid damage.
1 _t
-
trP
Motor thermal overload
The drive has tripped to prevent damage to the motor.
Try not to overload motor. Ensure sufficient cooling air is free to circulate around the motor and
that the entry and exit vents are not blocked or obstructed.

trp
Power stage trip
Check for short circuits on the motor and connection cable.
0
-
volt
Over voltage on DC bus
Check the supply voltage is within the allowed tolerance for the drive.
U
-
volt
Under voltage on DC bus
The incoming supply voltage is too low. This trip occurs routinely when power is removed from
the drive. If it occurs during running, check the incoming power supply voltage and all
components in the power feed line to the drive.
0
-
t
Heatsink over temperature
The drive is too hot. Check the ambient temperature around the drive is within the drive
specification (+50°C/+122F) . Ensure sufficient cooling air is free to circulate around the drive.
Increase the panel ventilation if required. Ensure sufficient cooling air can enter the drive, and
that the bottom entry and top exit vents are not blocked or obstructed.
U

t
Under temperature
Trip occurs when ambient temperature is less than
-
10°C/+14F. Temperature must be raised
over
-
10°C/+14F in order to start the drive.
E

External trip
Normally closed contact has opened for some reason. Check if the motor is too hot.

DC bus ripple too high
Check incoming supply phases are all present and balanced.

Input phase loss trip
Check incoming power supply phases are present and balanced.

Drive ambient temperature too high, check adequate cooling air is provided. Increase the panel
ventilation if required. Ensure sufficient cooling air can enter the drive, and that the bottom entry
and top exit vents are not blocked or obstructed.

F
Output fault
Indicates a fault on the output of the drive, such as one phase missing, motor phase currents
not balanced. Check the motor and connections.
