Request preparation for POWER-ON RESET
The DP master can check as follows, whether the power-on reset was executed:
– write 2 into P0972 and read-back the value
– write 1 into P0972 ––> POWER-ON RESET is requested
Read P0972 after communications have been established:
P0972 = 0? ––> the POWER-ON RESET was executed
P0972 = 2? ––> the POWER-ON RESET was not executed
Note:
After P0972=1, the link between the drive and SimoComU is interrupted with the following mes-
sage: ”Reading from the interface was interrupted due to time overflow”. The link is re-estab-
lished when SimoCom U is re-started.
