*1 The increment differs according to the inverter 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 The inverter regards the output current which is less than the specified current level (5% of the rated inverter current) as 0 A. Therefore, each
readout of an output current and output power may show "0" if a too small-capacity motor is used as contrasted with the inverter capacity and the
output current falls below the specified value.
*3 Setting of Pr.1018 Monitor with sign selection is required.
*4 This signal is available only 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.)

• Enter the full-scale value of the meter corresponding to a voltage of 10 VDC output via terminal AM. Enter the current value
(for example, 60 Hz or 120 Hz) at full scale of the meter (10 VDC voltmeter) installed between terminal AM and terminal
5. Output voltage is proportional to the frequency. (The maximum output voltage is 10 VDC.)
