Flexible
Powerful Starting Torque without Encoder
By applying the IPM motor, output of a zero speed at 200% torque without encoder are possible. This will lead to miniaturization of the constant torque machine and system cost down. When utilizing the induction motors with the advanced open loop vector control, tension control of the winder can be done without encoders, which will improve the wire savings and reliabilities.
Torque Control without Encoder
With the improvement performance of advanced vector controls, it can be installed without mounting the encoders. Reliabilities has increased due to needless of the encoders.
EZ Open Loop Vector Control Tuning-less even for Synchronous Motors!
Yaskawaʼs brand new EZ open loop vector control can drive both synchronous motors and induction motors and does not require any complicated tuning processes. Simply input the information on the motor nameplate. EZ open loop vector control can reduce trial operation time and minimize the number of pieces of equipment used by the same drive to run the induction and synchronous motors. Energy-saving control also makes it possible to operate with better efficient in comparison with the conventional drives.*
High-speed Operation
With the signifi cant improvement in the basic performances, induction motor and synchronous motor can drive up to 590 Hz*.
As a result, miniaturization of the machine from gear-less and motor miniaturization are possible.
