State output pin
Name Function
Data
type
Time when there is
a transition in an
output pin’s signal
from low to high
Time when there is a
transition in an output pin’s
signal from high to low
Error
An error occurs
in the motion
control function
block.
BOOL

Input values
are incorrect.

The source
specified has
been occupied.

There is a transition in
the Error output pin’s
signal from high to low
when there is a
transition in the Enable
input pin’s signal from
high to low.
3. Troubleshooting
Error Troubleshooting
The values of input pins in the motion
control function block are incorrect. Check whether the values of the input pins
are in the ranges allowed.
4. Modules which are supported
The motion control function block T_Interrupt supports AH05PM-5A, AH15PM-5A, AH10PM-5A,
and AH20MC-5A.
5.13.11 Absolute Encoder
1. Motion control function block
The motion control function block T_AbsEncoder is used to start the reading of the position of
an absolute encoder.
2. Input pins/Output pins

Data
type
Setting value Time when a value is valid
Channel Group number WORD K1~K4 (*1)
The value of the Channel
input pin is valid when there
is a transition in the Enable
input pin’s signal from low to
high.
Execute
The reading of the
position of an
absolute encoder
is enabled when
there is a
transition in the
Execute input
pin’s signal from
low to high.
BOOL True/False -
Bit
Resolution of an
absolute encoder
DWORD K1~K32 (*2)
When the motion control
function block is executed,
the value of the Bit input pin
is updated repeatedly.
