Note: While many K-1 drives are older, the 2021 context often refers to updated compliance documents, archived support manuals, or reseller documentation files maintained by distributors. 1. Overview of Tverter K1 Series VFD
For sleepy PID response, increase P8.09 (PID sleep frequency – e.g., 25Hz) and P8.10 (sleep delay – e.g., 30 seconds). This stops the pump during low demand, saving energy.
The best source for the original documentation is to contact Motortronics, which often holds archived files. tverter k1 series manual pdf 2021
Contact Motortronics for "Motortronics K1 drive" documentation, as they previously re-branded this unit.
The manual contains a list of error codes that appear on the display. Common codes include: Note: While many K-1 drives are older, the
To give you a better understanding of the Tverter K1 series, here are some key specifications:
Ensure the motor is completely disconnected from the mechanical load if performing a dynamic tune. This stops the pump during low demand, saving energy
To set acceleration time to 5 seconds:
: Ensure the motor's full load amps do not exceed the VSD's rated output before starting . Finding the PDF Manual

| Fault Code | Description | Likely Cause & Solution (from manual) | | ---------- | -------------------------------- | ------------------------------------------------------- | | | Overcurrent during acceleration | Short circuit at motor terminals; increase accel time. | | OU | Overvoltage during deceleration | Braking resistor too small; extend decel time (P0.05). | | SC | Short circuit (module fault) | Check motor insulation; replace IGBT module. | | OL | Motor overload | Increase P1.02 (motor current) slightly; reduce load. | | LU | Low voltage (undervoltage) | Check input supply; voltage sag. | | OH | Overheat (heatsink >85°C) | Clean fans; improve ventilation. | | CE | RS485 communication error | Check wiring and P9.00 (baud rate mismatch). |
