What to do if the TEC Inverter shows Output Over Current?
Check for short circuits on the motor and connection cable. 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.
What does it mean when my TEC TECDrive TEC-3-320153-104 Inverter 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.
What causes a TEC TECDrive TEC-3-320153-104 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 the TEC TECDrive TEC-3-320153-104 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 should I do if my TEC TECDrive TEC-3-320153-104 Inverter 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 should I do if my TEC TECDrive TEC-3-320153-104 Inverter displays '4-20mA Signal Lost'?
If the TEC Inverter displays '4-20mA Signal Lost', check the analog input connection(s).
What causes a TEC TECDrive TEC-3-320153-104 Inverter to display 'Drive internal temperature too high'?
A 'Drive internal temperature too high' error occurs when the drive ambient temperature is too high. Check that adequate cooling air is provided.
What does it mean when TEC Inverter is showing 'Under temperature'?
When TEC Inverter displays ‘Under temperature’, it means the ambient temperature is less than -10°C. The temperature must be raised over -10°C in order to start the drive.
What to do if TEC Inverter shows 'DC bus ripple too high'?
If the TEC Inverter displays 'DC bus ripple too high', check that the incoming supply phases are all present and balanced.

The TECDrive TEC-3 is an AC Variable Speed Drive designed for professional incorporation into complete equipment or systems as part of a fixed installation. It is distributed by TEC Electric Motors and is available in IP20 and IP66 (NEMA 4X) enclosed units. The drive supports motor power from 0.37 to 22kW (0.5 – 30HP) and operates on input voltages ranging from 110V to 480V.
The TECDrive TEC-3 is designed to control the speed of AC motors, offering precise and variable speed operation. It features a keypad and display for configuration and monitoring, allowing users to manage parameters, view operating displays, and reset faults. The drive supports various control modes, including Terminal Control, Keypad Control (uni-directional and bi-directional), Modbus Network Control, PI Control, and CANopen Control.
A key feature is the "Fire Mode" function, designed for emergency conditions. This mode ensures continuous operation of the drive even when it might otherwise trip, by disabling certain protection features like over-temperature, external trip, and phase imbalance. This allows the drive to continue operating to clear smoke or maintain air quality in critical situations.
The drive includes an internal motor thermal overload function (l.t-trP trip) to protect the motor. It also supports optional brake resistors for improved braking torque in applications requiring it. For communication, the TECDrive TEC-3 can be connected to a Modbus RTU network via an RJ45 connector, allowing for remote control and monitoring of parameters and drive status.
The TECDrive TEC-3 offers a user-friendly interface with a keypad and display for easy operation.
Routine maintenance is crucial for the longevity and optimal performance of the TECDrive TEC-3.
