T1-09: Motor No-Load Current
No.
Name
(Hex.)
T1-09 Motor No-Load Current
(0709)
Note:
The display units are different for different models:
• 0.01 A: 2001 to 2042, B001 to B018, 4001 to 4023
• 0.1 A: 2056 to 2082, 4031 to 4060
The value shown is the no-load current that the drive automatically calculates from the values set in T1-02 [Motor
Rated Power] and T1-04 [Motor Rated Current]. Set the no-load current shown on the motor test report. If the
motor test report is not available, do not change this parameter.
■
T1-10: Motor Rated Slip Frequency
No.
Name
(Hex.)
T1-10 Motor Rated Slip
Frequency
(070A)
Shows 0.000 Hz as the default value. Set the rated slip shown on the motor test report. If the motor test report is
not available, do not change this parameter.
■
T1-11: Motor Iron Loss
No.
Name
(Hex.)
T1-11 Motor Iron Loss
(070B)
Note:
The default setting is different for different motor codes and motor parameter settings.
The value shown is the E2-10 [Motor Iron Loss] or E4-10 [Motor 2 Iron Loss] for the motor output set in T1-02
[Motor Rated Power]. If the motor test report is available, enter the motor iron loss value to T1-11.
■
T1-12: Test Mode Selection
No.
Name
(Hex.)
T1-12 Test Mode Selection
(0BDB)
0 : No
1 : Yes
After Auto-Tuning, the drive automatically sets E2-02 [Motor Rated Slip] and E2-03 [Motor No-Load Current]
when you operate the motor for the first time in Drive Mode.
Note:
After Auto-Tuning is complete and you set the drive to Drive Mode, operate the motor in these conditions:
• Make sure that you connect all wiring between the drive and motor
• Make sure that a mechanical brake on the motor shaft is not locked
• Keep the motor-load ratio at 30%
• Hold constant speed for longer than 1 second at a minimum of 30% of the speed set in E1-06 [Base Frequency] (the default setting is
the same as the maximum frequency).
■
T1-13: No-load voltage
No.
Name
(Hex.)
T1-13 No-load voltage
(0BDC)
752
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the no-load current of the motor.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets motor rated slip.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the iron loss for calculating the energy-saving coefficient.
V/f OLV OLV/PM OLV/PM AOLV/PM EZOLV
Sets the function to enable Test Mode after Stationary Auto-Tuning. When you can operate the
motor with a light load attached after Stationary Auto-Tuning is complete, enable this parameter.
V/f OLV OLV/PM AOLV/PM EZOLV OLV/PM
Sets the no-load voltage of the motor. When the no-load voltage at rated speed is available, for
example on the motor test report, set the voltage in this parameter. If the no-load voltage is not
available, do not change this parameter.
