Description
Each of the last 8 faults is displayed individually.
The set frequency is displayed.
The motor speed is displayed (depending on the
settings of Pr.37 and Pr.144). (Refer to
During encoder feedback control operation or
under Vector control, the actual motor speed
according to encoder signals is displayed.
The motor torque is displayed as a percentage
(0% under V/F control), considering the rated
torque as 100%.
The DC bus voltage value is displayed.
Brake duty set in Pr.70 for the regeneration unit
set in Pr.30 is displayed.
The motor thermal cumulative value is displayed,
considering the thermal operation level as 100%.
The peak value of output current, which is
constantly stored, is displayed. (It is reset with
every startup of the inverter.)
The DC bus voltage peak value, which is
constantly stored, is displayed. (It is reset with
every startup of the inverter.)
The power at the inverter input side is displayed.
The power at the inverter output side is displayed.
Torque current is displayed as a percentage,
considering Pr.56 setting value as 100%
(considering the motor rated torque as 100%
under Real sensorless vector control or Vector
control).
The motor excitation current is displayed.
The number of pulses per motor rotation during
orientation control operation or in the position
control mode is displayed. (The output voltage is
displayed when a Vector control option is not
installed.)
The cumulative energization time since the
inverter shipment is displayed.
The number of times an integrated value has
reached the maximum value of 65535 hours can
be checked in Pr.563.
Monitoring is enabled only during orientation
control operation. (The output voltage is displayed
when a Vector control option is not installed.)
(Refer to page 554.)
The cumulative operation time is displayed.
The number of times an integrated value has
reached the maximum value of 65535 hours can
be checked in Pr.564. Use Pr.171 to reset the
cumulative operation time. (Refer to
The output current value is displayed as a
percentage, considering the inverter rated current
value as 100%.
Readout (%) = present output current value /
inverter rated current value × 100
The cumulative energy based on the monitored
output power is displayed. Use Pr.170 to reset it.
