Interpret Status Indicators

The operation panel contains six status indicators as defined in the following
table.
Table 25 - Status Indicator Legend
Status Indicators Description
ON PWM switching is being performed.
READY
OFF PWM switching is not being performed.
ON Fault occurred or the error log is being displayed.
FAULT
OFF Normal operation
ON The operation panel is in Program mode.
PROGRAM
OFF The operation panel is in Monitor mode.
A ON The rms value (in Amps) of the monitored input current is displayed.
• AC input voltage (rms) value is displayed
V ON
• DC-bus voltage value is displayed
ON Monitored power-running (kW) value is displayed.
kW
Flashing Monitored power (regenerated) (kW) value is displayed
The load ratio
A, V, kW OFF
displayed when A, V, and kW are all OFF in Monitor mode.
(1) The displayed value of input current is only an approximate value and no accuracy can be guaranteed. If you need an accurate
value, measure it by using a dedicated measuring device.
The operation panel operates in the two modes:
• In Monitor mode, you can monitor various operating conditions
including input current of the 8720MC-RPS unit and DC-bus voltage,
for example.
• In Program mode, you can view and change parameter values, and
examine the error log.

Monitor Mode

To select a value to monitor, press
Pressing or increments you through the each of the displays.
In Monitor mode, the PROGRAM status indicator is OFF, indicating that the
operation panel is not in Program mode. When any fault occurs, the operation
panel cannot be changed to Monitor mode.

is a ratio of the input current to the rated current. Load ratio (in %) is
or until the desired value is displayed.
