Fuji Electric FRENIC-Ace series - U Codes (Customizable Logic Operation)

5.3 Description of Function Codes
5-248
5.3.10 U codes (Customizable logic operation)
The customizable logic function allows the user to form a logic or operation circuit for digital/analog input/output
signals, customize those signals arbitrarily, and configure a simple relay sequence inside the inverter.
In the customizable logic, one step (component), depending on the type, is composed of:
(1) Digital 2 inputs, digital 1 output + logical operation (including timer)
(2) Analog 2 inputs, analog 1 output/digital 1 output + numerical operation
(3) Analog 1 input, digital 1 input, analog 1 output + numerical operation, logical operation
and a total of 200 steps can be used to configure a sequence.

Customizable logic cancellation
command “CLC”
Allows to stop all the customizable logic operations by assigning “CLC” to
a general-purpose input terminal and turning it ON.
It is used when you want to deactivate the customizable logic temporarily.
Customizable logic timer
cancellation command “CLTC”
Resets the timer, counter and all the previous values used in customizable
logic by assigning “CLTC” to a general-purpose input terminal and turning
it ON. It is used when a customizable logic is changed or if you want to
synchronize it with external sequence.
If you use the customizable logic cancellation command and customizable logic timer cancellation
command, the inverter can unintentionally start because the speed command is unmasked, depending
on the structure of the customizable logic. Be sure to turn OFF the operation command to turn it
ON.
A physical injury may result.
A damage may result.
