Settings On The Inverter - Hitachi SJ700-2 Series Instruction Manual

Chapter 2 Creation and Execution of a User Program

2.6 Settings on the Inverter

The easy sequence function is a feature of the SJ700 Series Inverter. The easy sequence function
enables the inverter to access the variables written in a user program via inverter input/output terminals.
Programming software EzSQ provides the reserved variables for control access to the inverter via
external terminals. You can combine these variables as required to control inverter operation.
Some reserved variables require the inverter settings to enable the variables. Also, the settings of
frequency commands, operation commands, and input/output terminals on the inverter must follow those
specified in the user program.
The table below lists the items, reserved variables, and function codes that must be configured when
using the easy sequence function. For details on the reserved variables, see the explanation of settings
related to the easy sequence function in Chapter 5.
