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. Smooth starts using a high starting torque of 200%.
•
Dynamic torque-vector control incorporating leading technologies
enables a high starting torque of 200% (at 0.5 Hz).
• Operation can be started using a high starting torque of
200% even if large-sized item is being loaded. Even if there
is a change in the type of item being conveyed, dynamic
torque-vector control quickly and flexibly accommodates
such change. Consequently, more efficient and continuous
operation can be realized without causing a tripping.
2. Droop operation function enabling balanced load
operation using two motors for long distance
conveyors
• Long distance conveyors transporting heavy items usually
have two motors at each end of the conveyor. Smooth
operation is difficult due to the unbalance of the load being
conveyed.
To eliminate this problem, an inverter is installed for each
motor and droop operation is set, enabling optimal operation
by maintaining a good load balance between the motors.
3. Highly efficient operation using multistep fre-
quency operation
• Even if the carrying amount varies, the operating frequency
can be easily changed using the multistep frequency
function. The carrying items can be transported smoothly
without stopping the conveyor.
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.
