3.3.14. Object 6125h: AI Autozero
Writing a signature “zero” to this object causes a modification of object 7124h value, AI Input
Offset, such that object 7130h [AI Input PV] becomes zero. This zeroing cycling is
performed once, upon reception of the signature to the appropriate subindex, but the
zeroing procedure can be performed any time, as many times as required.
The signature is a 32-bit unsigned number, composed of the ASCII codes of the signature
characters, according to the following table:
MSB
LSB
o r e z
6Fh 72h 65h 7Ah
On reception of the correct signature to an appropriate subindex, the 18 Digital Input will
perform the zeroing operation for that input, and then confirm the SDO transmission.
