Why does my TEC Inverter display 'External trip'?
The TEC Inverter displays 'External trip' because an E-trip was requested on digital input 3, likely because a normally closed contact has opened. If a motor thermistor is connected, check if the motor is too hot.
What does it mean when my TEC Inverter shows 'Output Fault'?
An 'Output Fault' on the TEC Inverter indicates a problem on the output of the drive, such as a missing phase or unbalanced motor phase currents. Check the motor and its connections.
How to fix an Autotune Fault on TEC TECDrive TEC-3?
An autotune fault indicates that the motor parameters measured during autotune are incorrect. Check the motor cable and connections for continuity, and ensure all three phases of the motor are present and balanced.
What should I do if my TEC TECDrive TEC-3 shows a Power stage trip error?
If your TEC Inverter displays a power stage trip error, check for short circuits on the motor and connection cable.
What does it mean when the TEC TECDrive TEC-3 displays 'Under voltage on DC bus'?
An 'Under voltage on DC bus' error indicates that the incoming supply voltage is too low. Check the incoming power supply voltage and all components in the power feed line to the drive.
What causes a TEC Inverter to trip due to Motor Thermal Overload (I2t)?
The TEC Inverter tripped to prevent damage to the motor because it delivered more than 100% of the value in P-08 for an extended period.
What does it mean when my TEC TECDrive TEC-3 displays 'Over voltage on DC bus' and how can I resolve it?
An 'Over voltage on DC bus' error suggests the supply voltage is outside the allowed tolerance. Verify the supply voltage is within the correct range. If the fault occurs during deceleration or stopping, try increasing the deceleration time or install a suitable brake resistor and activate the dynamic braking function.
