V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the frequency reference value. Parameter o1-03 [Keypad Display Unit Selection] sets the
display units.
Unit: 0.01 Hz
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the output frequency. Parameter o1-03 [Keypad Display Unit Selection] sets the display units.
Unit: 0.01 Hz
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows 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 detected motor speed. Parameter o1-03 [Keypad Display Unit Selection] sets the display
units.
Unit: 0.01 Hz
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the output voltage reference.
Unit: 0.1 V
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Shows the DC bus voltage.
Unit: 1 V
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Shows the internally-calculated output power.
When you change A1-02 [Control Method Selection], it will also change the signal level of the
analog output.
• A1-02 = 0: Drive capacity (kW)
• A1-02 = 2: Motor Rated Power [E2-11] (kW)
• A1-02 = 5, 6: PM Motor Rated Power [E5-02] (kW)
• A1-02 = 8: Motor Rated Power [E9-07] (kW)
Unit: When the drive model changes, the display units for this parameter also change.
• 0.01 kW: B001 - B018, 2001 - 2042, 4001 - 4023
• 0.1 kW: 2056 - 2082, 4031 - 4060
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
