Frequency Monitor Reference (Pr.55); Current Monitor Reference (Pr.56) - Mitsubishi Electric FR-F800 Instruction Manual

(M) Monitor display and monitor output signal
Frequency monitor reference (Pr.55)
• Set the full-scale value for outputting the monitored items of output frequency, frequency setting value to the terminals FM,
CA and AM.

Current monitor reference (Pr.56)
• Output current, Output current peak value, Motor excitation current and monitor from the terminals FM, CA and AM.
• For the FM-type inverters, set the full-scale value of the connected meter when the pulse speed of terminal FM is 1440
pulses/s (50k pulses/s).
Set the current to be indicated as the full scale value to the meter (1 mA analog meter) connected between terminal FM and
SD.
Pulse speed is proportional to the monitored value of output current. (Maximum pulse train output is 2400 pulses/s (55k
pulses/s).)
• For the CA-type inverters, set the full-scale value of the connected current meter when output current of terminals CA is 20
mA. Set the current to be indicated as the full scale value on the meter (20 mADC ammeter) connected between terminals
CA and 5.Output current is proportional to the monitored value of output current. (The maximum output current is 20
mADC.)
• For the calibration of terminal AM, set the full-scale value of the connected current meter when the output voltage of
terminal AM is 10 VDC.
Set the current to be indicated as the full scale value on the meter (10 VDC voltmeter) connected between terminal AM and
5.
Output voltage is proportional to the monitored value of output current. (The maximum output voltage is 10 VDC.)

• For the FM-type inverters, set the full-scale value of the
connected meter when the pulse speed of terminal FM is
1440 pulses/s (50k pulses/s). Set the frequency to be
indicated as the full scale value on the frequency meter (1
mA analog meter) connected between terminal FM and SD.
(For example, 60 Hz or 120 Hz.) Pulse speed is
proportional to the output frequency of the inverter.
(Maximum pulse train output is 2400 pulses/s (55k pulses/
s).)
• For the CA-type inverters, set the full-scale value of the
connected meter when output current of terminal CA is 20
mA. Set the frequency to be indicated as the full scale value
on the meter (20 mA DC ammeter connected between
terminal CA and 5; for example, 60 Hz or 120 Hz. Output
current is proportional to the frequency. (The maximum
output current is 20 mA DC.)
• For the calibration of terminal AM, set the full-scale value of
the connected meter when output voltage of terminal FM is
10 VDC. Set the frequency to be indicated as the full scale
value on the meter (10 VDC voltmeter) connected between
terminal AM and 5. (For example, 60 Hz or 120 Hz) Output
voltage is proportional to the frequency. (The maximum
120Hz
output voltage is 10 VDC.)
