Parameters (M) Monitor display and monitor output signal
FR-A800 5 - 345
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 mA DC.)
●
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 V DC.
Set the current to be indicated as the full scale value on the meter (10 V DC voltmeter) connected
between terminal AM and 5.
Output voltage is proportional to the monitored value of output current. (The maximum output
voltage is 10 V DC.)
Torque monitor reference (Pr. 866)
●
Set the full scale value when outputting the current monitor from terminal the FM, CA or AM.
●
For the FM-type inverters, set the full-scale value of the connected torque meter when the pulse
speed of terminal FM is 1440 pulses/s (50k pulses/s). Set the torque to be indicated as the full scale
value on the meter (1 mA analog meter) connected between terminals FM and SD.
Pulse speed is proportional to the monitored value of torque. (Maximum pulse train output is
2400 pulses/s (55k pulses/s).)
●
For the CA-type inverters, set the full-scale value of the connected torque meter when output
current of the terminal CA is 20 mA DC.
Set the torque to be indicated as the full scale value on the meter (20 mA DC ammeter) connected
between terminals CA and 5.
Output current is proportional to the monitored value of torque. (The maximum output voltage
is 20 mA DC.)
●
For the calibration of terminal AM, set the full-scale value of the connected torque meter when
the output voltage of terminal AM is at 10 V DC.
Set the torque to be indicated as the full scale value on the meter (10 V DC voltmeter) connected
between terminal AM and 5.
Output voltage is proportional to the monitored value of torque. (The maximum output voltage
is 10 V DC.)
