SSI Error Bit:
Defines the position of the error bit (if available with the encoder in use).
00: no error bit available
13: bit 13 represents the error bit
25: bit 25 represents the error bit etc.
Errors indicated by the encoder can be read out via serial code ;9 (semicolon
nine, error indication = 2000hex). In case of an error, the “Error Bit active”
box on the PC screen appears red.
It is also possible to use pin 25 of the parallel output for error indication
(see DIL switch settings).
SSI Error Bit
Polarity:
Defines the polarity of the Error Bit
0:
Bit is LOW in case of error
1:
Bit is HIGH in case of error
P01 (x), P01 (y)
etc:
Linearisation registers
(see section
Direction:
This parameter changes the internal direction of counting (0 or 1), provided
the unit operates in Round Loop mode.
Parallel Inv:
When you change this register from 0 to 1, the data on the parallel output
will be inverted.
Parallel Value:
The numerical value of this parameter appears directly at the parallel
output, provided the register „Parallel Mode“ has been set to a value
greater than 2 before. The serial access code of Parallel Value is “48” and
the setting can be changed at any time via serial link
This function may be useful for testing of function and wiring of the parallel output.
