Test Mode Selection
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.
Note:
You must first set T1-10 = 0 [Motor Rated Slip Frequency = 0 Hz] to enable this
parameter.

No-load voltage
Sets the no-load voltage of the motor. If you know the no-load voltage at the rated speed in
a test report, set that voltage value. If you do not know the no-load voltage, do not change
from the initial value.
Note:
• To get the same qualities as a Yaskawa 1000-series drive or previous models, set this
parameter = T1-03 [Motor Rated Voltage] value.
• The default value is different for different models.
