*1 Frequency setting to output terminal status on the PU main monitor are selected by "other monitor selection" of the parameter unit (FR-PU04, FR-PU07).
*2 Position pulse and orientation status function when used with an option (FR-A7AP). When orientation control is invalid, "0" remains displayed and these
functions are invalid.
*3 Feedback pulse functions when the option (FR-A7AP) is used and vector control is performed.
*4 The cumulative energization time and actual operation time are accumulated from 0 to 65535 hours, then cleared, and accumulated again from 0.
When the operation panel (FR-DU07) is used, the time is displayed up to 65.53 (65530h) on the assumption that 1h = 0.001, and thereafter, it is
added up from 0.
*5 The actual operation time is not added up if the cumulative operation time before power supply-off is less than 1h.
*6 When using the parameter unit (FR-PU04/FR-PU07), "kW" is displayed.
*7 The setting depends on the inverter capacity. (FR-A720-02150(FR-A740-01100) or less / FR-A720-02880(FR-A740-01440) or more)
*8 Since the panel display of the operation panel (FR-DU07) is 4 digits in length, the monitor value of more than "9999" is displayed "----".
REMARKS
⋅ By setting "0" in Pr. 52, the monitoring of output frequency to alarm display can be selected in sequence by
⋅ When the operation panel (FR-DU07) is used, the displayed units are Hz, V and A only and the others are not displayed.
⋅ The monitor set in Pr. 52 is displayed in the third monitor position (The output voltage monitor is changed).
Note that load meter, motor excitation current, and motor load factor are displayed in the second monitor (output current).
Initial value
* The monitor displayed at powering on is the first monitor. Display the monitor you want to display on the first monitor and hold down
for 1s. (To return to the output frequency monitor, hold down

Description
Display the number of pulses fed back from
the encoder during one sampling (display
during a stop).
Display energy saving effect monitor
You can change the monitor to power saving,
power saving average value, charge display
and % display using parameters.
(For details, refer to page 275)
Display the set point, measured value and
deviation during PID control (For details,
refer to page 360)
Display the input terminal ON/OFF status on
the PU (refer to page 253 for DU display)
Display the output terminal ON/OFF status
on the PU (refer to page 253 for DU display)
Display the input terminal ON/OFF status of
the digital input option (FR-A7AX) on the DU
(refer to page 253 for details)
Display the output terminal ON/OFF states of
the digital output option (FR-A7AY) or relay
output option (FR-A7AR) on the DU (refer to
page 253 for details)
Desired values can be output from terminal
FM and AM using the PLC function.
Refer to the FR-A700 PLC function
programming manual for details of the PLC
function.
