9.8. PROGRAMMING THE LENZE 644 INVERTER
The LENZE inverter can be programmed only by using the keypad eventually installed on-board the
machine.
With the inverter powered up, the display shows the parameters for function C50 (work frequency).
To display the other parameters:
1. Press the “^” or “∨” keys to increase or decrease the number of the displayed parameter. To
increase the scrolling speed, also hold down the “SH” key.
2. When the desired parameter is reached, press “PRG” to display its value.
3. To modify the value, press the “^” or “∨” keys to increase or decrease.
4. To save the modified value, simultaneously press the “SH” keys and then “PRG”: the display
reverts to showing the value of the selected main function.
Incorrect programming of the inverter may result in serious damage to the machine or
improper operation potentially hazardous for the user. Therefore, carry out this
operation only if certain of being able to perform the procedure correctly.
The table below shows the values of the function parameters:
MAIN PARAMETERS
