6.2.2 LECOM unit address (C0009)
The LECOM-A/B protocol uses the LECOM unit address to address the controller. The LECOM unit
address is set under codeC0009 at the controller. The addressmust only be used once. Thus, each
controller must get its own LECOM unit address.The values 00, 10, 20, 30, ..., 90 must not be set
since they are reserved for group addressing (see chapter 5).
The LECOM-A/B protocol enables controller groups. This allows a write request to be issued to
severaldrives at the sametime, e.g. to select new setpoints or enable or inhibit the controller. Select
via the following reserved LECOM unit addresses:
LECOM unit address C0009 for
group drives
LECOM unit addresses of the addresses controllers
00 all
10 11 to 19
20 21 to 29
30 31 to 39
40 41 to 49
50 51 to 59
60 61 to 69
70 71 to 79
80 81 to 89
90 91 to 99
Tip!
Pleasenotethat with LECOM controller addresses whichend witha 0, the controller does not return
an acknowledgement, i.e. the host does not recognize whether the controller received the data
correctly or not.
