Description
Display the set frequency.
Display the motor speed
(The display differs depending on the Pr. 37
and Pr. 144 settings. The running speed is the
actual speed by the encoder signal during
encoder feedback control and vector control.
For details, refer to page 251.)
Display the motor torque in percentage on the
assumption that the rated motor torque is 100%
(0% is displayed during V/F control)
Display the DC bus voltage value.
Brake duty set in Pr. 30 and Pr. 70
Display the motor thermal cumulative value
on the assumption that the thermal operation
level is 100%.
Retain the peak value of the output current
monitor and display (clears at every start)
Retain the peak value of the DC bus voltage
value and display (clears at every start)
Display power on the inverter input side
Display power on the inverter output side
Torque current is displayed in % on the
assumption that the Pr. 56 setting is 100%
(displayed on the assumption that rated
motor torque is 100% during sensorless
vector and vector control)
Display the excitation current of the motor
Display the number of pulses per rotation of
the motor when orientation control is valid (for
FR-A7AP/FR-A7AL)
Cumulative energization time since the
inverter shipment is displayed.
You can check the numbers of the monitor
value exceeded 65535h with Pr. 563.
Terminal FM:
1440 pulse/s is output when Pr. 291 = 0, 1.
50k pulse/s is output when Pr. 291
Terminal FM:
1440 pulse/s is output when Pr.291 = 0, 1.
50k pulse/s is output when Pr.291 ≠ 0, 1.
Terminal AM: 10V is output
Display only when orientation control is valid
(for FR-A7AP/FR-A7AL) (Refer to page 220)
Cumulative inverter running time is displayed.
You can check the numbers of the monitor
value exceeded 65535h with Pr. 564.
Use Pr. 171 to clear the value. (Refer to page
258)
On the assumption that the rated inverter
current value is 100%, the output current
value is displayed in %.
Monitor value = output current monitor value/
×
rated inverter current 100 [%]
Cumulative power amount is displayed
according to the output power monitor.
Use Pr. 170 to clear the value. (Refer to page
258)
