IP 266 Technical Description of the IP 266
In addition to incremental position encoders made by Siemens, you may also use
non-Siemens encoders which conform to the following specifications:
• Method of measurement: Incremental
• Supply voltage: 5 V or 24 V
• Output signals:
- Symmetrical encoders A signal
(5 V signals) B signal
R reference signal
A\ signal
B\ signal
R\ signal
- Asymmetrical encoders A* signal
(switching to P poten-
tial only) B* signal
24 V encoders R* reference signal
• Max. operating frequency
- 5 V encoder 500 kHz for 30 m cable
- 24 V encoder 100 kHz for 25 m cable
We would recommend the following cable for connecting the IP 266 when using
a Siemens encoder (6FC 9 320) for 5 V signals:
Order No.: 6ES5 705-7 ... 1
The three dots in the Order No. stand for the three-digit length code. You will
find a list of length codes in Catalog ST 52.1.
