Frequently asked questions

The UVtech HD71 offers three control modes: terminal, serial communication, and keypad. You can select the desired control mode through parameter P01.03. The default mode is keypad control.

You can use different reference sources to control the frequency of the drive. The available options include analogue reference, preset speed reference, E-pot reference, serial communication, keypad, potentiometer, and PID. You can select the desired reference source through parameter P01.04.

The UVtech HD71 provides four V/F control modes: standard, linear, user-defined, and ramp. These modes allow you to customize the V/F characteristics based on your application needs. You can select the desired mode through parameter P01.26.

To perform an auto-tune, set parameter P01.17 to 1. The drive will then automatically measure the motor parameters and store the values in the EEPROM. Ensure that you have correctly entered the motor rated voltage, current, frequency, speed, and power factor in parameters P01.12 to P01.19 before running the auto-tune.
