Name Description MFAO Signal Level
U2-01
(0080)
Current Fault Shows the fault that the drive has when viewing the monitor. No signal output available
U2-02
(0081)
Previous Fault Shows the fault that occurred most recently. No signal output available
U2-03
(0082)
Freq Reference@Fault 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
No signal output available
U2-04
(0083)
Output Freq @ Fault 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
No signal output available
U2-05
(0084)
Output Current@Fault 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
No signal output available
U2-06
(0085)
Motor Speed @ Fault 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
No signal output available
U2-07
(0086)
Output Voltage@Fault 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
No signal output available
U2-08
(0087)
DC Bus Voltage@Fault 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
No signal output available
U2-09
(0088)
Output Power @ Fault 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
No signal output available
U2-10
(0089)
Torque Ref @ Fault 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%
No signal output available
U2-11
(008A)
Input Terminal Status @
Fault
Shows the status of the MFDI terminals at the most recent fault where = ON and = OFF.
For example, U2-11 shows when terminals S1 and S3 are ON.
Use U1-10 [Input Terminal Status] to monitor the actual MFDI terminal status.
bit0 : Terminal S1
bit1 : Terminal S2
bit2 : Terminal S3
bit3 : Terminal S4
bit4 : Terminal S5
bit5 : Terminal S6
bit6 : Terminal S7
bit7 : Not used (normal value of [ ]).
No signal output available
