9.5. PROGRAMMING THE HITACHI SJ100 INVERTER
The inverter can be programmed using the special keypad installed on board the machine. It is
necessary to correctly configure the values of the main functions labeled with an F, and those of the
extended functions labeled with A, b, C and H.
If programming an inverter that is not assembled on the machine, before proceeding
with the other operations:
• connect the mains power supply to terminals L1 and N;
• place a jumper between terminals 1 and P24;
• place a jumper between terminals AL1 and AL0.
When the inverter is energized, function parameter d01 appears on the display: this is the inverter
output frequency toward the motor.
To display the inverter monitor parameters (d type) or those of another main function:
1. Press the "1" or "2" key until the desired main function appears.
2. Press the "FUNC" key once to display the value of the parameter.
3. To modify the value, press the "1" key to increase or the "2" key to decrease.
4. To exit and save the modified value, press the "STR" key; to exit without saving press the
"FUNC" key. After this, the display will revert to showing the selected main function.
To display the extended function parameters:
1. Press the "1" or "2" keys to display the desired function: A--, b--, C-- o H--.
2. Press the "FUNC" key to display the code of the extended function: for example the display will
show A01.
3. Press the "1" or "2" key until the desired extended function appears. The display of the extended
function parameters is cyclical, and after scrolling the type A parameters it goes on to type b and
so on.
4. Press the "FUNC" key once to display the value of the parameter.
5. To modify the value, press the "1" key to increase or the "2" key to decrease.
6. To exit and save the modified value, press the "STR" key; to exit without saving press the
"FUNC" key. After this the display reverts to showing the selected extended function.
7. To exit extended function menu, press the "FUNC" key until it shows A--, b--, C-- o H--.
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.
WARNING: when the programming has been completed, remember to set displayed the
value of the parameter d01 (motor frequency).
