3.5 Which SSI-format do the configurations need ? 

 
 

PNO configurations 

All  PNO  configurations  (class  1/16,  class  1/32,  class  2/16,  class  2/32)  exclusively 
need the TR-SSI-format: 
 

TR encoder type 

 

 

SSI binary with 28 data bits and 15 bit checksum 

 

Output format 

Revolutions, 12 bit 

Steps / Revolution, 16 bit 

TR checksum 

28 data bits 

15 bit

LSB (2

Programmings <  12  bits  (revolutions) are completed MSB-sided accordingly with 
"0".  Programmings  <  16  bit  (steps/revolution)  are  completed  LSB-sided  (starting 
from 2

15

) accordingly with "0". 

The  bit  pattern  entered  into  the  output  format  corresponds  to  the  encoder 
resolution 4096 steps/revolution x 1024 revolutions. 

 
 
 
 

TR configuration 

The TR configuration 

"Box+rotary encoder TR Gear"

 can be operated with different 

SSI-formats: 
 

Rotary encoders 

 

1.  TR encoder type 

 

 

SSI binary with 28 data bits and 15 bit checksum (see PNO configurations) 

 
 

2.  General encoder type 

 

 

SSI binary with 24 data bits, 4096 steps/rev. x 4096 rev., tree-format 

 

Output format 

Revolutions, 12 bit 

Steps / Revolutions, 12 bit

The  encoder  absolutely  must  have  the  programming,  which  is  specified  above.  The 
SSI-BOX  is  reduced  in  the  programming  (see  use  notes  of  this  configuration  on 
page 23).
