0.4K-NA.)
CAUTION
•When the wiring length of the 0.1K and 0.2K of the three-phase 200V and
single-phase 100V class and the 0.4K and 0.75K of the three-phase 400V class
is 30m (98.43 feet) or more, set the carrier frequency to 1kHz.
•When automatic torque boost is selected in Pr. 98 "automatic torque boost
selection (motor capacity)", the wiring length should be 30m (98.43 feet)
maximum. (Refer to page 57.)
