12.16 2019h – Power supply fault counter
The number of electrical power supply faults (voltage below minimum threshold of 21.6 V DC) can
be accessed using the following SDO command:
Client (master)  server (LEMCOM)
CAN-ID
(600h+ID)
620h
Command
40h
Object L

Object H
20h
Subindex
Module no.+1
Byte 0
00h
Byte 1
00h
Byte 2
00h
Byte 3
00h
The subindex is used to define the module to query (from 1 to 16):
- Subindex = 0x01  request for counter value on master module (address #0)
- …
- Subindex = 0x10  request for counter value on secondary module at address #15
The reply is as follows:
Server (LEMCOM)  Client (master)
