Multi-Speed And Jog Frequency Setting - Hitachi WJ200 Series Instruction Manual

Multi-speed and Jog Frequency Setting

Multi-speed – The WJ200 inverter has the capability to store and output up to 16 preset
frequencies to the motor (A020 to A035). As in traditional motion terminology, we call

digital inputs to the inverter. The inverter applies the current acceleration or
deceleration setting to change from the current output frequency to the new one. The
first multi-speed setting is duplicated for the second motor settings (the remaining 15
multi-speeds apply only to the first motor).
