Synchronisation cycle
The controllers/PLCs receive the sync telegram/signal and compare the time between two
LOW−HIGH edges of the signal to the specified cycle time (C1121).

Lenze Selection
[C1121] Sync cycle 2 1 {1 ms} 13 Synchronisation cycle
Definition of the cycle time of the
sync telegram/signal.
· Parameterisation is only
required for the slave!
· The value set in C1121 is the time between two sync telegrams/signals of the master.

IMPORTANT
Lenze Selection
[C1122] Sync phase 0.460 0 {0.001 ms} 6.5 Synchronisation phase
Phase shift between the sync
telegram/signal and the start of the
internal control program.
Monitoring the synchronisation (time slot)
The variable CAN_bSyncInsideWindow_b can be used for monitoring the synchronisation.
Code LCD
Possible settings
IMPORTANT
Lenze Selection
[C1123] Sync window 0 0 {0.001 ms} 6.5 Synchronisation window
If the sync telegram/signal sent by
the master is in this "time slot",
CAN_bSyncInsideWindow_b
switches to TRUE.
