Hitachi WJ200 Series

3−19
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
this
multi-speed profile capability. These preset frequencies are selected by means of
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).

There are two ways for speed selection, that are “binary operation” and “bit operation”.
For binary operation (
A019=00), you can select 16 speeds by combination of 4 digital
inputs. And for bit operation (
A019=01), you can select 8 speeds by using 7 digital inputs.
Please refer to the following figures for detailed explanation.
