Manual torque boost
(1) The values set up with C004/C005 are outputted. C004 set a percentage level where motor
voltage selection is 100%.
(2) When using the manual torque boost, it should be noted that overuse will cause saturation of
the motor and may cause damage.
(3) The manual torque boost break point (C005) sets a percentage level where the base
frequency voltage is 100%.
(4) If the reduced voltage start selection(b003) is enabled, the torque boost is not valid. Set the
reduced voltage start selection(b003) to 0.
In case of C003 = 0, C004 = 10.0, C005 = 5.0 In case of C003 = 0, C004 = 5.0, C005 = 10.0

11.2.2
Automatic torque boost
(1) The output voltage is adjusted automatically by condition of the load.
(2) When using automatic torque boost it important that the following two parameters are set
correctly.
(3) In case of adding over-current protection at deceleration time, set AVR selection ON(A53=0)
all the time.
