5.3 Description of Function Codes 5.3.10 U codes (Customizable logic operation)

processing
cycle
1 ms (max. 10 steps), 2 ms (max. 20 steps), 5 ms (max. 50 steps), 10 ms (max. 100
steps), 20 ms (max. 260 steps):
The cycle can be selected with function code U100, but it is dependent on the
maximum number of steps.
(1) All external input signals up to the maximum step are latched at the beginning
of the processing cycle to maintain synchronism.
(2) Calculations are performed in order from step 1 to the maximum step. The
calculation cycle differs depending on the number of steps.
(3) If output for a certain step is input to the next step, output for steps with high
processing priority can be used with low priority steps in the same cycle.
(4) 14 customizable logic output signals (CLO1 to 14) are updated simultaneously
at the end of the processing cycle.
1 ms (max. 10 steps), 2 ms (max. 10 steps), 5 ms (max. 30 steps), 10 ms (max. 50
steps), 20 ms (max. 100 steps):
(1) External input signals corresponding to all customizable logics for steps 1 to
200 are latched at the beginning of each cycle to maintain synchronism.
(2) Calculation for the prescribed number of steps is repeatedly carried out every 1
ms/2 ms/5 ms/10 ms/20 ms cycle.
(3) If output for a certain step is input to the next step, output for steps with high
processing priority can be used with low priority steps in the same cycle.
(4) If outputting the 14 customizable logic output signals (CLO1 to 14) from a step
for a different cycle, updating and outputting are performed for each cycle in
which the step is executed.
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.
Failure to observe this could result in injury.
Failure to observe this could result in failure.
