• 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.)

Output of negative signals enabled when Pr.290 Monitor negative output selection = "1 or 3"
 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/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 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 output pulse
train is 2400 pulses/s (or 55k pulses/s).)
• For the CA type inverter, enter the full-scale value of the current meter corresponding to a current of 20 mADC output via
terminal CA. Enter the current value at full scale of the meter (20 mADC ammeter) installed between terminal CA and
terminal 5. Output current is proportional to the output current monitored. (The maximum output current is 20 mADC.)
• 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 a meter used to monitor the output torque via terminal FM/CA 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 (or
50k 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 output pulse train is
2400 pulses/s (or 55k pulses/s).)
• For the CA type inverter, enter the full-scale value of the torque meter corresponding to a current of 20 mADC output via
terminal CA. Enter the torque value at full scale of the meter (20 mADC ammeter) installed between terminal CA and
terminal 5. Output current is proportional to the torque monitored. (The maximum output voltage is 20 mADC.)
• 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 (Pr.291)
• Two kinds of pulse trains can be outputted via terminal FM.
• When Pr.291 Pulse train I/O selection = "0 (initial value) or 1", pulse train is output via terminal FM, with a maximum
output of 8 VDC and 2400 pulses/s.
The pulse width can be adjusted on the operation panel or the parameter unit by using the calibration parameter C0
(Pr.900) FM/CA 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).
