V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the contents of the MEMOBUS/Modbus communication error where
error".
For example, U1-19 shows
bit0 : CRC Error
bit1 : Data Length Error
bit2 : Not used (normal value of [ ]).
bit3 : Parity Error
bit4 : Overrun Error
bit5 : Framing Error
bit6 : Timed Out
bit7 : Not used (normal value of [ ]).
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the frequency to pulse train input terminal RP.
Unit: 1 Hz
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the ID.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the ROM ID.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the virtual analog input value.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the fault that the drive has when viewing the monitor.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the fault that occurred most recently.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
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
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
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
