Ch.1
In the table are showed the values of IS ctrl src from SBI word, DGFC word or Int IS ctrl if:
IS ctrl src = Int IS ctrl.
No. bit Name Description
Access (Read/ Write)
Default
0-1 - Not used - -
It indicates the encoder index edge polarity:
0= rising edge
1= falling edge
3-Not used - -
It sets the qualifier input state to activate the encoder index reading:
=0, switched off when dig.input7=0
=1, switched off when dig.input7=1
=2, through signal = 0
=3, through signal = 1
It points out for whitch encoder the values of this parameter are reported:
=0, operations requested on the Std Encoder input
=1, operations requested on the Exp Encoder input
7-Not used - -
Control function of the encoder inedx reading
=0, swtched off, function disabled
=1, once, enables the reading of the first index signal edge only.
=2, continuous, enables the reading of the index signal

For the Index storing function, the control Registers are not available via the keypad and are to be used for
the configuration and the data reading. These are:
L index register Ipa 9556
H index register Ipa 9555
In the table are showed the registers values:
Ipa No. bit Name Description
Access
(Read/
Write)
Default
It indicates to which encoder is used for index storing:
=0, register data are referred to the Std Encoder input
=1, register data are referred to the Exp Encoder input
Actual Qualifier input value (digital input 7):
=0, qualifier input level is low
=1, qualifier input level is high
Status of the acquisition function; as:
0=OFF
1=Once, storing is not executed yet
2=Once, storing is already executed
3=Continuous
Position counter value corresponding to the index.
Value is only valid when STANLT is equal to 2 or 3
