 T3-01: Inertia Tuning Frequency Reference
There is normally no need to change this parameter from the default value.
Sets the frequency of the test signal applied to
the motor during Inertia Tuning. Increasing the value may be beneficial
when working with high inertia loads.
 T3-02: Inertia Tuning Reference Amplitude
There is normally no need to change this parameter from the default value.
Enter the amplitude of the test signal applied to the
motor during Inertia Tuning. If the load inertia is too large and causes
problems during Inertia Tuning, try decreasing the value. If a fault occurs when T3-01 is set to low value, the situation
may be remedied by adjusting T3-02.
 T3-03: Motor Inertia
Enter the inertia of the motor. This value is used to determine the load inertia using the test signal response. The default
setting is for a YASKAWA standard motor as listed in the motor inertia table.
Note: The display resolution depends on the rated output power of the drive after the Drive Duty has been set in parameter C6-01.
Drives with a maximum output up to 30 kW will display this value in units of 0.0001 kgm
2
. Drives with a maximum output 37 to
160 kW will display this value in units of 0.001 kgm
2
. Drives with a maximum output 185 kW and above will display this value
in units of 0.01 kgm
2
. Refer to A1000 Model Selection on page 29 for details.
 T3-04: ASR Response Frequency
Sets the response frequency (reciprocal of the step response time constant) of the system or the connected machine. The
drive uses this value and the load inertia to fine-tune the speed control loop gain (C5-01, ASR Gain 1). Oscillation may
result if the value input here is higher than the actual response frequency of the system.
