*1 Differs according to the capacity. (Increment left of a slash for FR-A820-03160(55K) or lower, FR-A840-01800(55K) or lower. Increment right of
a slash for FR-A820-03800(75K) or higher, FR-A840-02160(75K) or higher.)
*2 When the output current is less than the specified current level (5% of the rated inverter current), the output current is monitored as 0 A. Therefore,
the monitored value of an output current and output power may be displayed as "0" when using a much smaller-capacity motor compared to the
inverter or in other instances that cause the output current to fall below the specified value.
*3 Setting of Pr.1018 Monitor with sign selection is required.
*4 The setting is available for the standard model.
*5 The setting is available only in Pr.158 (terminal AM).
 Frequency monitor reference (Pr.55)
• Enter the full scale value of a meter used to monitor the output frequency, the frequency setting value, or the dancer main
speed setting via terminal FM/CA or terminal AM.
• For the FM type inverter, enter the full-scale value of the meter corresponding to a pulse train of 1440 pulses/s (or 50k
pulses/s) output via terminal FM. Enter the frequency value (for example, 60 Hz or 120 Hz) at full scale of the meter (1 mA
analog meter) installed between terminal FM and terminal SD. Pulse speed is proportional to the output frequency of the
inverter. (The maximum output pulse train is 2400 pulses/s (or 55k pulses/s).)

• For the CA type inverter, enter the full-scale value of the meter corresponding to a current of 20 mADc output via terminal
CA. Enter the current value (for example, 60 Hz or 120 Hz) at full scale of the meter (20 mADC ammeter) installed between
terminal CA and terminal 5. Output current is proportional to the frequency. (The maximum output current is 20 mADC.)
