values, name of set value and possible input value range will be changed. If input value is out of
range, it will not be accepted.)
The following step is showing input method. First, enter the input/revise value that you want to
input. Press ENTER
and VERIFY
button. When you enter wrong value while doing
input/revise operation, press ESC
button and re-enter a value. Previous frequency of (2) in
figure 8 displays set value prior to input/revise operation. New frequency of (3) displays the
wanted input/revise value. Press enter
button reflects set value to the inverter and displays
current frequency. When inputs/revises another set values, the method is the same as above.
[Warning]
When warning occurs, warning sign will be displayed on the operator in real-time. Warning sign is
displayed in operation monitoring board, operation controlling board, CELL monitoring board, CTPT
monitoring board, and the function selecting menu screen. The displaying location is in between
the naming part and the communication normal/abnormal flickering LED which is located at upper
left in each screen. If warning does not occur, nothing is displayed at this location. Warning sign
and the reason of warning are shown below.
[1] ‘Cell_low voltage’: DC-Link voltage of power cell falls below 70%(595[V]) out of rated voltage.
[2] ‘CAN initialization failure’: Occurs when the initialization of CAN communication between 18
power cells and main controller fails.
[3] ‘Fan MC1 failure’: Fan MC1 of the inverter panel is in abnormal state.
[4] ‘Operator communication failure’: Communication failure between operator and main
controller.
[5] ‘Breakdown’: Inverter breakdown.
