Chapter 5 Function Code
- When PID control is valid: The normal/inverse operation for output of the PID controller (frequency setting)
Table 5.4-67
PID Control Operation Select (J01) Input Signal IVS Operation
OFF Normal operation
1: For processing (normal operation)
ON Inverse operation
OFF Inverse operation
2. For processing (inverse operation)
ON Normal operation
- When PID control is invalid: The normal/inverse operation for the manual frequency setting
Table 5.4-68
Selection of Normal/Inverse Operation
(Frequency Command 1) (C53)
Input Signal IVS Operation
0: Normal operation - Normal operation
1: Inverse operation - Inverse operation
When process control is performed by the PID control function integrated in the inverter,
switching the normal operation/inverse operation IVS is used for switching of normal
operation/inverse operation of output of the PID controller (frequency setting). It is irrelevant to
switching the normal operation/inverse operation of the manual frequency setting.

Function code J01 to J19, J56 to J62)
Assignment of interlock IL (Function code data = 22)
In a configuration where a magnetic contactor is installed in the power output (secondary) circuit of the
inverter, the momentary power failure may not be detected accurately only by the momentary power failure
detection function in the inverter. In this case, using the interlock signal IL and inputting the digital signal can
restart the operation smoothly after momentary power failure. (
Function code F14)
Table 5.4-69
Input Signal IL Meaning
OFF No momentary power failure has occurred.
ON
Momentary power failure has occurred. (Restart after a
momentary power failure is valid)
Assignment of link operation select LE (Function code data = 24)
When LE is on, operate the motor by following the frequency command or operation command from the
communication (RS-485 communication or field bus) set by the link function (operation select) (H30) or bus
function (operation select) (y98).
When LE is not assigned, it is same as when LE is on. (
Function code H30, y98)
Assignment of universal DI U-DI (Function code data = 25)
This function enables monitoring of digital signals from the periphery equipment of the inverter via RS-485
communication or field bus by connecting to the digital input of the inverter. Digital signals assigned to the
universal DI can be used as a simple monitor regardless of the inverter operation.
Accessing to universal DI via the RS-485 communication or fieldbus communication, see the
respective instruction Manuals.
Assignment of activation property select STM (Function code data = 26)
This function enables to select whether auto search is executed or not at the time of start (auto search
executed without stopping the motor).
