9.3 History buffer
Via the history buffer (0x10F3), the controller can access the last 32 messages of the i700 servo
inverter.
• The history buffer is saved persistently to the i700 servo inverter.
• The structure of the history buffer corresponds to a ring buffer:
• As long as there is free history buffer space available, a message is placed in the next free slot
in the buffer.
• If all buffer slots are full, the oldest message is deleted for a new one.
• The latest messages will always remain available.
• See the "Diag code" (32-bit word) of every single message to find out which axis the message
refers to:
