A0:A3 drive slave address (Pr27+1), valid values 1..15.
Note 1: as for the “real time mode”, bit 41.9 is set to 1 every synchronism message receiving
via SBCCAN.
Therefore, it is possible to check the communication status between Master and Slave via
CAN bus through a simple pico-PLC program.
The pico-PLC code on the drive be as follows:
…
Ld 41.9
Out 41.5
Rst 41.9
…
If the check of the communication status between Master and Slave via CAN bus is
implemented into the drive pico-PLC, the test is executed every 6.144 [ms] (i.e. minimum
execution time of pico-PLC program) or multiples.
