7.11.10.3 Absolute position (encoder 1)
The system position results from the position value - system offset
(Ec.60 = Ec.31 - Ec.33; Ec.61 = Ec.32 - Ec.34)
7.11.11 Further parameters / encoder
The following parameters are required only for specic encoder interfaces and are explained more closely in
the appropriate documentation.
7.11.11.1 SSI encoder at channel 1
Ec.53: Encoder 1 SSI multiturn res.
Default value 0
Value range 0…13
Number of bits for all revolutions
Ec.43: SSI data code channel 1
Default value 0
Value range 0…1
0 binary
used data format of the encoder
1 Gray
Ec.54: Encoder 1 SSI mode
Default value 0
Value range 0…3
0 Standard
1 Singleturn 25 bit
SSI singleturn encoder which shall be read out with
25bit
2 Linear (SIKO AE 111)
Especially for SIKO encoders at linear motors
3
Only as SSI (chan-
nel 1)
Value 3 allows to adjust a SinCos SSI encoder interface
by way that only the SSI signals are evaluated. This
function is supported upto encoder interface software
date 19.04.2012. The encoder interface software date
can be seen in parameter In.32.
7.11.11.2 SSI encoder at channel 2
Ec.21: SSI multiturn res.
Default value 12
Value range 0…13 Number of bits for all revolutions
Parameter Ec.24 must be set to 0 in order to use 13 bits in parameter Ec.21.
