●When tuning result is beyond specific range
Sometimes, special-purpose motors such as high-speed motor
and high-slip motor etc. cannot be tuned correctly. In case that
improper tuning is performed, "tEr1" and "tEr2" will be displayed
and fault trip will occur. Just press STOP SW button to reset.

Voltage Compensation Constant

During vector control or when auto torque boost is performed through V/F
control, necessary voltage compensation constants should be set.
Setting value (V)
The setting value of voltage compensation constant can be calculated by the
following formula.
Setting value = R x I R: including one-phase resistance of wiring
motor, related parameters are as follows.
