Chapter 3 – Configuring the Inverter
The configuration of inverter parameters will depend on the specific functionality and performance required for
your application. The basic functionality of the board is designed to interface with a two pushbutton,
two-position (two-speed) momentary contact type pendant commonly used for crane and hoist applications. This
is the basis for the descriptions of the functions of the board presented in this manual. The setup in the table
below will result in infinitely variable speeds between the programmed MIN and MAX speeds. The defined
functions of the pushbuttons are as follows:
UP, first detent: UP – accelerate to minimum speed
UP
UP, second detent: UP – increase speed while held, up to MAX speed (or go to second speed, see page 11)
DOWN, first detent: DOWN – accelerate to minimum speed (RESET fault when inverter is
DOWN
DOWN, second detent: DOWN – increase speed, up to MAX speed (or go to second speed, see page 11)
Pushing either the UP or DOWN pushbutton to the first position causes the inverter to go to the minimum
configured speed in that direction. Pushing that button further to its second position will cause speed to increase
in that direction. Releasing back to first position will hold that last speed. Releasing the pushbutton all the way
will cause the inverter to come to a stop. If that button is re-pressed to the first position before stop is reached,
that speed will be maintained. In order to achieve this basic functionality, the installation of the EzSQ C&H
program must be downloaded to the inverter through the use of Hitachi ProDriveNext software. The software is
available to download from our company website.
This program also will require a change in parameters that differ from factory default values, as described in the
following table. The application will also write to these parameters as needed.

Set a value between 1 and 3600 seconds, depending on application. If P031
Note 1
is set to 03, acceleration is controlled by EzSQ. This is field adjustable.

07 Tells the inverter to read speed reference from EzSQ program. See note 3.
01 Tells the inverter to take the RUN command from the control terminals.
Depending on the motor limits and application requirements, set the

appropriate value, (Must be equal or greater than P120 parameter)
Note 1 Usually the same value as A004. See note 3. This is field adjustable.
Lowest speed for continuous operation (MIN speed), usually 6 to 10 Hz or
Note 1 so. This is the speed that will be commanded at the first pushbutton position.
See note 3. This is field adjustable.
