Current communication phase
The current communication phase (binary encoded) can be read with the lower three bits
(0, 1, 2):
– 000b: Slave is in phase 0 (start phase)
– 001b: Slave is in phase 1 (configuration phase)
– 010b: Slave is in phase 2 (parameterization phase)
– 011b: Slave is in phase 3 (extended parameterization phase)
– 100b: Slave is in phase 4 (operating phase)
Communication error bits according to sercos
If an interface error occurs, one of bits 3 - 13 in "S-0-0014 Interface status" os set.
The communication error bits are only cleared by the device when the corresponding
interface error is no longer present and the "S-0-0099 Reset class 1 diagnostic" command
was started.
