Cause: Regenerative energy from the motor is feeding back into the drive, or the input main voltage is too high.
The DC bus voltage is too high. This usually occurs during deceleration. Increase the decel time ( F_02 ) or install a braking resistor.
You may have better luck searching for the Motortronics K1 or Boston Gear T-Verter manuals, as they are technically the same hardware.

Analog input terminals for speed control. A standard 10kΩ potentiometer connects across +10V and GND, with the wiper connected to AI (Analog Input, 0-10VDC or 4-20mA).
Keypad potentiometer, digital display, and programmable I/O. 🔌 Hardware Installation and Wiring
Single-phase 110V, Single-phase 220V, Three-phase 220V, and Three-phase 460V. Output Frequency Range: Typically 0.1 to 400 Hz.
Ideal for AC motor speed control, conveyor systems, and pumps.
For users avoiding direct keypad operation, external analog controls can be wired using the standard control block:
Before applying power, ensure your control and power wiring match the factory standards: Main AC power input terminals.
. They retain archived physical and digital files for legacy clients and can often email you the file.
