• 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.)

 Current monitor reference (Pr.56)
• Enter the full scale value of a meter used to monitor the output current, the output current peak value, or the motor
excitation current 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 current value at full scale of the meter (1 mA analog meter) installed between terminal FM and
terminal SD. Pulse speed is proportional to the output current monitored. (The maximum pulse train output is 2400 pulses/
s.)
• Enter the full-scale value of the current meter corresponding to a voltage of 10 VDC output via terminal AM. Enter the
current value at full scale of the meter (10 VDC voltmeter) installed between terminal AM and terminal 5. Output voltage is
proportional to the output current monitored. (The maximum output voltage is 10 VDC.)
 Torque monitor reference (Pr.866)
• Enter the full-scale value of the meter used to monitor the output torque via terminal FM or terminal AM.
• For the FM type inverter, enter the full-scale value of the torque meter corresponding to a pulse train of 1440 pulses/s
output via terminal FM. Enter the torque value at full scale of the meter (1 mA analog meter) installed between terminal FM
and terminal SD. Pulse speed is proportional to the torque monitored. (The maximum pulse train output is 2400 pulses/s.)
• Enter the full-scale value of the torque meter corresponding to a voltage of 10 VDC output via terminal AM. Enter the torque
value at full scale of the meter (10 VDC voltmeter) installed between terminal AM and terminal 5. Output voltage is
proportional to the torque monitored. (The maximum output voltage is 10 VDC.)
 Terminal FM pulse train output
• The maximum pulse train output of terminal FM is 8 VDC 2400 pulses/s.
The pulse width can be adjusted on the operation panel by using the calibration parameter C0 FM terminal calibration.
• A 1 mA full-scale DC ammeter or a digital meter can be used to give commands (such as inverter output frequency
command).
