Heartbeat; Os Synchronization - BONFIGLIOLI Vectron Active Cube User Manual

Heartbeat

The heartbeat uses the producer/consumer method. The inverter as heartbeat con-
sumer can monitor up to three heartbeat producers. The inverter can also send the
heartbeat message (as heartbeat producer). The heartbeat contains the NMT state
of the producer.
The heartbeat consumer function is set by object
Time
. After setting the object the Monitoring of the heartbeat message(s) starts
with reception of the first heartbeat message.
If the inverter does not receive a producer heartbeat message within the specified
consumer heartbeat time, a heartbeat event is triggered. The reaction to this heart-
beat event is defined by objects

11.10 OS Synchronization

The operating System (OS) of the frequency inverter can be synchronized to the
PLC or other devices. The synchronization of the OS enhances the performance of
the complete plant. Synchronization is used to eliminate phase deviations of the
CPUs between master and slave devices, so that calculations are done at the same
time. Note, that only small deviations of the CPU clock frequencies between devices
(i.e. different CPU Quartz cock frequencies) of ± 1 ‰ can be compensated. The
synchronization time must be natural number as multiplier from 1 ms.
Synchronization via CANopen:
When using CANopen
and off. Synchronization can be done with CANopen
Synchronization via Systembus:
When using CANopen
set to either CANopen, Systembus or it can be switched off. Synchronization can be
done with Systembus SYNC telegrams or Systembus RxPDO telegrams.
Note: When synchronizing the OS via CANopen
