7.7 INVERTER
7.7.1 Checking the Parameters
With the digital operator's panel attached to the inverter, all
parameters can be set and checked. Operate the digital operator's panel
with the power to the oscillator turned on.
The parameters of an inverter purchased by FANUC are set before
shipment from the factory. So, usually, the parameters need not be
changed. If parameters need to be modified for a reason, detach the
cable connected to terminal No. 2 (soft lock signal) of the inverter
terminal block.
(1) Names and descriptions of the components of the digital operator's panel
Name Description
Monitor Displays settings such frequency and output current values.
RUN (operation) lamp Turned on when the inverter is running.
Program lamp Turned on when the monitor displays the setting of each function.
Blinks when a warning is given (when a setting is incorrect).
POWER lamp Power lamp of the control circuit
ALARM lamp Turned on when the inverter trips
Monitor lamp Lamp for indicating the display status of the monitor.
Hz: Frequency, V: Voltage, A: Current,
kW: Power, %: Ratio
Operation command indication lamp Turned on when the operation command destination is set to the operator.
Operation key Key for stopping the motor.
This key, however, is enabled only when the operation command destination is
set to the operator. (Check that the operation command indication lamp is on.)
STOP/RESET key Used to stop the motor or reset an alarm.
FUNC (function) key Used to enter the monitor mode, basic setting mode, extended function mode,
and function mode.
STR (store) key Used to store set values. (Be sure to press this key when changing set values.)
Up/down key Used to change the extended function mode, function mode, or set values.
