5.3 Description of Function Codes
5-108
• When process control is performed by the PID processor integrated in the inverter:
The terminal command Hz/PID (“Cancel PID control”) can switch PID control between enabled (process is to be
controlled by the PID processor) and disabled (process is to be controlled by the manual frequency setting). In
either case, the combination of the “PID control” (J01) or “Selection of normal/inverse operation for frequency
setting 1” (C53) and the terminal command IVS determines the final operation as listed Table 5.3-8 and Table
5.3-9.
Table 5.3-8 When PID control is enabled:
The normal/inverse operation selection for the PID processor output (reference frequency) is as follows.
PID control (Mode selection) (J01) Terminal command “IVS” Action
1: Enable (normal operation)
OFF Normal
ON Inverse
2: Enable (inverse operation)
OFF Inverse
ON Normal
Table 5.3-9 When PID control is disabled:
The normal/inverse operation selection for the manual reference frequency is as follows.
Selection of normal/inverse operation
for frequency setting 1 (C53)
Terminal command “IVS” Action
0: Normal operation - Normal
1: Inverse operation - Inverse
When process control is performed by the PID control facility integrated in the inverter, the “IVS” is used
to switch the PID processor output (reference frequency) between normal and inverse, and has no effect
on any normal/inverse operation selection of the manual frequency setting.

■
Interlock – “IL” (Function code data = 22)
In a configuration where a magnetic contactor (MC) is installed in the power output (secondary) circuit of the
inverter, the momentary power failure detection feature provided inside the inverter may not be able to accurately
detect a momentary power failure by itself. Using a digital signal input with the interlock command IL assures the
accurate detection. (

Function code F14)
Terminal command “IL” Meaning
OFF No momentary power failure has occurred.
ON
A momentary power failure has occurred. (Restart after a
momentary power failure enabled)
■
Cancel torque control -- “Hz/TRQ” (Function code data = 23)
When torque control is enabled (H18 = 2 or 3), assigning the terminal command “Hz/TRQ” (Cancel torque control)
to any of the general-purpose digital input terminals (data = 23) enables switching between speed control and
torque control.
Cancel torque control signal “Hz/TRQ” Operation
ON Cancel torque control (Enable speed control)
OFF Enable torque control
■
Select link operation (RS-485, BUS option) – “LE” (Function code data = 24)
Turning this terminal command “LE” ON gives priority to frequency commands or run commands received via the
RS-485 communications link (H30) or the fieldbus option (y98). No LE assignment is functionally equivalent to the
“LE” being ON. (
