*1 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.
*2 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, frequency setting value, or dancer main speed
setting via terminal FM 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 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 pulse train output is 2400 pulses/s.)
