*1 Frequency setting to output terminal status on the PU main monitor are selected by "other monitor selection" of the parameter
unit (FR-PU04V/FR-PU07).
*2 Position pulse and orientation status function when used with an option (FR-A7AP). If a value is set without using an option,
the display remains 0.
*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. (55K or less/75K 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
as ----.

*10 The monitor set in [Pr. 52] is displayed in the third monitor position. (The output voltage monitor is changed.) Note that load meter,
motor exciting current, motor load factor are displayed in the second monitor position (output current monitor).
Example: When [Pr. 52 = 20] (cumulative energization time), the monitor is displayed on the operation panel as described below.

(minus) output is at reverse rotation.
*15 When outputting from terminal DA1 of the built-in option FR-A7AZ (when [Pr. 838] is set), + (plus) voltage is at forward rotation drive /
reverse regeneration, and - (minus) voltage is made at reverse drive/ forward regeneration.
*16 When outputting from terminal DA1 of the built-in option FR-A7AZ (when [Pr. 838] is set), + (plus) voltage is made at forward / reverse
drive, and - (minus) voltage is at forward/ reverse regeneration.
*17 Torque monitor can be set only to [Pr. 838].

Displays the transistor thermal heat
integrated value. (Inverter overload
trip (E.THT) occurs at 100%.)
Displays the PTC thermistor
resistance input value to terminal 2
when PTC thermistor protection is
valid.
