These brands labeled the K1 specifically as the "T-Verter." Since they are largely out of the VFD business, archived manuals are typically found on third-party industrial repositories.
These drives are commonly found in applications including:
: Default settings allow speed changes via the keypad. To use an external potentiometer or remote inputs, specific parameters (often F19 or F20 ) must be modified .
Check fan functionality and ambient temperature. 5. Summary of Technical Specifications Input Voltage: Typically 200-240V, single or three-phase. Control Method: Simple V/F (Voltage/Frequency) ratio. Input/Output: Flexible I/O for external control signals.
Since the K1 is a legacy product, most available "manuals" are scanned copies or technical overviews from third-party automation sites: Sites like Industrial Monitor Direct
Assigns speed command authority. This can be assigned to the local keypad keys or an analog input line (such as a 0–10VDC source or a 4–20mA current loop). Advanced Functions & Dynamic Controls (F_12 to F_71)
: Manuals hosted on Chinese websites may be uploaded by users and not always officially sanctioned by Taian. Always verify the document's authenticity against your physical inverter.
Check for unusual operating noises or component discoloration.
Use shielded, twisted-pair cables for signal wiring to avoid EMI interference. 5. Key Parameter Programming
Maintain at least 10cm of clear space above and below the drive, and 5cm on the sides to ensure optimal airflow.
The K1 series, often marketed as the T-Verter by Boston Gear/Motortronics, serves as a fundamental Variable Speed Drive (VSD) solution. Speed control of 3-phase induction motors.
Programs the secondary terminal strip. This configures the drive for specialized remote operations, including INC/DEC (Increment/Decrement) pulse commands for remote digital control.
Measure input terminal voltage; check fuses and circuit breakers; verify all supply wiring connections are tight. Err11: Motor Overload (OL1)
provide recent (2025/2026) technical guides for parameter references and configuration. Scanned versions of the original K1 Series AC Servo Driver Manual
Set to 0 for keypad arrows; 2 for AI1 (0-10V potentiometer). Acceleration Time 1 Adjust based on load inertia (e.g., 5.0s to 30.0s). P0-12 Deceleration Time 1 Adjust based on application requirements. P0-17 Motor Rated Power Model Dependent Input exact nameplate kW rating. P0-18 Motor Rated Voltage 380V / 220V Input exact nameplate voltage. P0-19 Motor Rated Current Model Dependent Input exact nameplate amperage. Motor Auto-Tuning Procedure
, as doing so immediately destroys the internal IGBT switching blocks.
