IF52
SSI Offset
This register defines the electrical zero position of the encoder with respect to
the mechanical zero position. When the ROUND LOOP function is not active
(
Round Loop = 0), the SSI Offset value is subtracted from the SSI position
reading, which can also cause negative results. When the ROUND LOOP function
is active,
SSI Offset
displaces the mechanical zero position, but always within
positive values only. See also
Round Loop
item and the relevant example.
SSI Hold polarity
It sets the polarity of the HOLD signal available in terminal 10. See “5.3 HOLD
input” on page 36.
0 HOLD signal is active HIGH
1
HOLD signal is active
LOW

SSI Error Bit
This register defines the position of the error bit, if available for the encoder you
use. Errors indicated by the encoder can be read out via serial code ,, ;9 “
(semicolon nine, error indication = 2000hex). In case of error, the ERROR BIT
ACTIVE items in the OUTPUTS box will appear red in your PC screen. It is also
possible to use pin 25 of the parallel output for error indication (see section “6 -
DIL switch settings“ on page 39).
00
no error bit available
13
bit 13 represents the error bit
25
bit 25 represents the error bit, and so on
SSI Error Bit Polarity
This register defines the polarity of the error bit.
0
Bit is LOW in case of error
1
Bit is HIGH in case of error
