Example of Operation Time Scheme
Alternatively, you may use the integrated sequence by which some of the actions a
b
ove are automatically
performed by the inverter itself. For details, refer to the description of
ISW50 and ISW60.
■ Cancel PID control -- Hz/PID (Function code data = 20)
Turning this terminal command ON disables the PID control.
If the PID control is disabled with this command, the inverter runs the motor with the reference frequency manually set
by any of the multi-frequency, keypad, analog input, etc.
Terminal command
Hz/PID Function
OFF Enable PID control
ON Disable PID control/Enable manual frequency settings
( Refer to the descriptions of J01 through J19 and J56 through J62.)
■ Switch normal/inverse operation -- IVS (Function code data = 21)
This terminal command switches the output frequency control between normal (proportional to the input value) and
inverse in analog frequency setting or under PID process control. To select the inverse operation, turn the
IVS ON.
The normal/inverse switching operation is useful for air-conditioners that require switching between cooling
and heating. In cooling, the speed of the fan motor (output frequency of the inverter) is increased to lower the
temperature. In heating, it is reduced to lower the temperature. This switching is realized by this IVS terminal
command.
