Caution
The information described in this catalog is for the purpose of selecting the appropriate products.
Before actually using this product, be sure to read the instruction manual carefully to ensure proper
operation.
1. Greatly reduced motor wow
• With our unique, new control method, motor wow at low
speed has been reduced by more than one half (as com-
pared with a conventional Fuji Inverter).
2. Slip compensation control function enabling
constant speed operation of grinders
• By setting the slip compensation amount, constant grinder
rotating speed can be maintained irrespective of whether the
grinding amount is large or small.
3. Smooth starts using a high starting torque of
200%
• Dynamic torque-vector control incorporating leading tech-
nologies enables a high starting torque of 200% (at 0.5 Hz).
4. Unnecessary to resort to any special sound-
proofing measures; Fuji inverter drives a motor
with silent motor sound.
• We have succeeded in eliminating most of the unpleasant
motor sound that usually comes from the motor which is
driven by the inverter.
The sound levels are comparable to those of commercial
power sources.
The inverter meets strict restrictions for motor sound.
