Name Description MFAO Signal Level
U1-01
(0040)
Frequency Reference Shows the frequency reference value. Parameter o1-03 [Keypad Display Unit Selection] sets the
display units.
Unit: 0.01 Hz
10 V = Maximum frequency
(0 V to +10 V)
U1-02
(0041)
Output frequency Shows the output frequency. Parameter o1-03 [Keypad Display Unit Selection] sets the display units.
Unit: 0.01 Hz
10 V = Maximum frequency
(0 V to +10 V)
U1-03
(0042)
Output Current 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
10 V = Drive rated current
U1-04
(0043)
Control method selection Shows the drive control method.
0 : V/f Control
2 : Open Loop Vector
5 : PM Open Loop Vector
6 : PM Advanced Open Loop Vector
8 : EZ Vector Control
No signal output available
U1-05
(0044)
Motor Speed Shows the detected motor speed. Parameter o1-03 [Keypad Display Unit Selection] sets the display
units.
Unit: 0.01 Hz
10 V = Maximum frequency
(0 V to +10 V)
U1-06
(0045)
Output Voltage Ref Shows the output voltage reference.
Unit: 0.1 V
200 V Class: 10 V = 200
Vrms
400 V Class: 10 V = 400
Vrms
U1-07
(0046)
DC Bus Voltage Shows the DC bus voltage.
Unit: 1 V
200 V Class: 10 V = 400 V
400 V Class: 10 V = 800 V
U1-08
(0047)
Output Power 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
10 V: Drive capacity (motor
rated power) kW
(0 V to +10 V)
U1-09
(0048)
Torque Reference Shows the internal torque reference value.
Unit: 0.1%
10 V = Motor rated torque (0
V to +10 V)
U1-10
(0049)
Input Terminal Status
Shows the status of the MFDO terminal where = ON and = OFF.
For example, U1-10 shows when terminals S1 and S3 are ON.
bit0 : Terminal S1 (MFDI 1)
bit1 : Terminal S2 (MFDI 2)
bit2 : Terminal S3 (MFDI 3)
bit3 : Terminal S4 (MFDI 4)
bit4 : Terminal S5 (MFDI 5)
bit5 : Terminal S6 (MFDI 6)
bit6 : Terminal S7 (MFDI 7)
bit7 : Not used (normal value of [ ]).
