Shows the fault that the drive has when viewing the monitor.
Shows the fault that occurred most recently.
Shows the frequency reference at the fault that occurred most recently.
Use U1-01 [Frequency Reference] to monitor the frequency reference value.
Unit: 0.01 Hz
Shows the output frequency at the fault that occurred most recently.
Use U1-02 [Output Frequency] to monitor the actual output frequency.
Unit: 0.01 Hz
Shows the output current at the fault that occurred most recently.
Use U1-03 [Output Current] to monitor the actual output current. The keypad shows the value of U1-
03 in amperes (A).
When looking at the monitor through MEMOBUS/Modbus communications, the current is "8192 =
drive rated current (A)". Calculate the current from the monitor value that is in at MEMOBUS/
Modbus communications using "Numerals being displayed / 8192 × drive rated current (A).
Unit: When the drive model changes, the display units for this parameter also change.
• 0.01 A units: B001 - B018, 2001 - 2042, 4001 - 4023
• 0.1A units: 2056 - 2082, 4031 - 4060
Shows the motor speed at the fault that occurred most recently.
Use U1-05 [Motor Speed] to monitor the motor speed.
Unit: 0.01 Hz
Shows the output voltage reference at the fault that occurred most recently.
Use U1-06 [Output Voltage Ref] to monitor the output voltage reference.
Unit: 0.1 V
Shows the DC bus voltage at the fault that occurred most recently.
Use U1-07 [DC Bus Voltage] to monitor the DC bus voltage.
Unit: 1 V
Shows the output power at the fault that occurred most recently.
Use U1-08 [Output Power] to monitor the output power.
Unit: 0.1 kW
Shows the torque reference at the fault that occurred most recently as a percentage of the motor rated
torque.
Use U1-09 [Torque Reference] to monitor the torque reference.
Unit: 0.1%
Shows the status of the MFDI terminals at the most recent fault where
For example, U2-11 shows
Use U1-10 [Input Terminal Status] to monitor the actual MFDI terminal status.
