(5) Setting the Low Cut-off Level
Set the low cut-off level such that the output will be
cut off to zero when it is below the low cut-off level.
Access the parameter LOW_CUT, and set the low cut-
off level.

Access the parameter IO_OPTS, and set Low cutoff
to on (true). Resetting Low cutoff to off (false) disables
the low cut-off function.
(6) Setting the Damping Time Constant
Access the parameter PV_FTIME, and set the time
constant (in seconds) of the first-order lag filter.
(7) Carrying Out the Simulation
You can carry out a simulation for an AI block
by manually setting the input value (within the
measurement range) and status.
Access the Simulate Status component of the
parameter SIMULATE, and set the code of the desired
status to be set in simulation mode.

Access the Simulate En/Disable component of the
parameter SIMULATE, and enable or disable the
simulation:
2 = Active
1 = Disable

Access the Simulate Value component of the
parameter SIMULATE, and set the desired value.
An AI block performs the specified actions using:
• Values of Simulate Status and Simulate Value
in SIMULATE as its input value and status when
the Simulate En/Disable value is 2.
• Values of Transducer Status and Transducer
Value in SIMULATE as its input value and
status when the Simulate En/Disable value is
1.
See Section 6.3 for further details of the simulation
function.
A2.5 Setting Up DI Blocks
DI blocks are used to output limit switch signals
from the transducer block. Since each of the four DI
blocks in a YTA320 has independent parameters,
set the parameters for each DI block you use. The
following shows the procedure to set up the DI1
block for example.
(1) Setting the Channel
Specify the limit switch whose signal should be
input from the transducer block.
Access the parameter CHANNEL, and set the number
corresponding to the limit switch whose signal you want
to input:
7 = LIMSW_1_VALUE_D (Limit switch 1)
8 = LIMSW_2_VALUE_D (Limit switch 2)
9 = LIMSW_3_VALUE_D (Limit switch 3)
10 = LIMSW_4_VALUE_D (Limit switch 4)
(2) Setting the Damping Time Constant
Access the parameter PV_FTIME, and set the delay
time in seconds, which is the time period by which a
change in output should be delayed after a change in
input.
(3) Carrying Out the Simulation
You can carry out a simulation for a DI block
by manually setting the input value (within the
measurement range) and status.
Access the Simulate Status component of the
parameter SIMULATE_D, and set the code of the
desired status to be set in simulation mode.

Access the Simulate En/Disable component of the
parameter SIMULATE_D, and enable or disable the
simulation:
2 = Active
1 = Disable

Access the Simulate Value component of the
parameter SIMULATE_D, and set the desired value.
A DI block performs the specified actions using:
• Values of Simulate Status and Simulate Value
in SIMULATE_D as its input value and status
when the Simulate En/Disable value is 2.
• Values of Transducer Status and Transducer
Value in SIMULATE_D as its input value and
status when the Simulate En/Disable value is
1.
See Section 6.3 for further details of the simulation
function.
