Additions to the A1000 and V1000 frequency inverters are available from Yaskawa with output frequencies of up to 1000Hz. Both are available for 230 or 400V mains voltage operation with nominal power ratings of 0.4 to 110 or 0.4 to 160kW for the A1000 inverter and 0.1 to 3 or 0.1 to 15kW for the V1000. Multi-functional inputs and outputs provide simple PLC functions. There is also an integrated Safe Torque Off function. Series A1000 functions can be used in conjunction with permanent magnet motors without rotational speed feedback for energy-saving drives. The DriveWizardPlus operating and parameterisation software for PCs streamlines inverter commissioning and parameteriation. DriveWizardEZ programming software allows users to generate application-specific functions.
