Diagnostic and Status Messages
Apart from some status and display parameters that are valid for all
operating modes, the parameters P-0-0089, Status word for
synchronous operating modes and P-0-0152, Synchronization
completed are available for diagnosing the synchronization modes.
The feedback signaling that the slave axis has been synchronized takes
place in bit 8 of parameter P-0-0089, Status word for synchronous
operating modes.
P-0-0089, Status word for synchronous operating modes:
• bit 8 = 0 → slave axis has not been synchronized
• bit 8 = 1 → slave axis has been synchronized
In synchronous position control modes the drive sets bit 8 when the
following applies:
02280S0753)-0-P(0048)0S(x
sync
−−<−−−+
In the case of velocity synchronization the drive sets bit 8 when the
following applies:
01830S0040)-0-S(0037)0S(dx
sync
−−<−−−+
The information on whether a synchronization process is active or has
been completed is mapped to bit 0 of parameter P-0-0152,
Synchronization completed.
P-0-0152, Synchronization completed:
• bit 0 = 0 → synchronization running
• bit 0 = 1 → synchronization completed
As regards the generation of bit 0 in parameter P-0-0152, the following
cases have to be distinguished for the operating modes "phase
synchronization" and "electronic cam shaft":
• First synchronization process:
Bit 0 is set when the distance up to the absolute or relative position
has been traveled.
• Cyclic normal operation:
When bit 0 has been set, the fact of whether bit 0 is cleared for the
duration of the following travel reaction when the additive position
command value (S-0-0048) is changed, depends on the setting of bit 0
in parameter P-0-0155, Synchronization mode. If bit 0 = 1 in
parameter P-0-0155 ("register controller" mode), bit 0 remains set in
parameter P-0-0152.
