12.5 Digital Input (DI) Function Definition (for Absolute System)

Setting Value: 0x1D
DI Name
When ABSE is activated (ON), it can initialize an Absolute
ABSE
System and enable ABSQ, ABSC, ABSR, and ABSD as well.
Please refer to Figure 12.3 and 12.4 for timing diagram.
No matter what the original functions of DI4, DO2, and DO3
are, they will be switched to the function of ABSQ, ABSR, and
ABSD respectively. DI4 will be changed to ASDQ, DO2 will be
changed to ABSR, and DO3 will be changed to ABSD. The ABSC
can be set via the parameter setting (DI function setting).
When ABSE is ON, the setting value of parameter P2-13 cannot
be changed.
Setting Value: When ABSE is activated (ON), DI4 is switched to the function of ABSQ to
replace the DI function set by parameter P2-13.
DI Name
When ABSQ is activated (ON), it indicates that the host
ABSQ is
controller has read and put its data at ABSD for next bit
controlled
communication. When ABSQ is OFF, the host controller will
send the command for requesting next bit communication.
by DI4
This function is for communication handshaking during digital
I/O signal transmission. ABSQ is effective only when the
digital input, ABSE is ON. Please refer to Figure 12.4 for timing
diagram.
Setting Value: 0x1F
DI Name
When ABSC is activated (ON), the pulse number of absolute
ABSC
encoder will be reset to zero, and PUU number will be reset to
the setting value of P6-01. ABSC is effective only when the
digital input, ABSE is ON. Please refer to Figure 12.3 for timing
diagram.
