(2) Display set frequency during
stop (Pr. 52)
⋅ When Pr. 52 is set to "100", the set
frequency monitor is displayed during
a stop and the output frequency
monitor is displayed during operation.
(LED of Hz flickers during stop and is
lit during running.)
REMARKS
⋅ During an error, the output frequency at error occurrence appears.
⋅ During MRS, the values displayed are the same as during a stop.
⋅ During offline auto tuning, the tuning status monitor has priority.
(3) Operation panel (FR-DU07) I/O terminal monitor (Pr. 52)
⋅ When Pr. 52 is set to any of "55 to 57", the I/O terminal states can be monitored on the operation panel (FR-DU07).
⋅ The I/O terminal monitor is displayed on the third monitor.
⋅ The LED is on when the terminal is on, and the LED is off when the terminal is off. The center line of LED is always on.
