Axis synchronization via terminal control (X5/E5)
There are two different transmission channels for the sync signal and the process signal.
l The process signals are connected via a freely selectable input channel (e.g. AIF interface, DF
input).
l The sync signal is sent via terminal X5/E5.
Application examples:
l Input of cyclic, synchronized position setpoint information for multi-axis positioning via
different bus systems (e.g. Interbus).
l Synchronization of internal processing cycles of the FB to higher-level process controls.
7.6.74.2 Cycle times
Sync cycle time (SYNC CYCLE)
The master (e.g. PLC) sends ther periodic sync telegram
1)
(sync signal
2)
).
The controllers (slaves) receive the sync telegram and compare the time between two LOW-HIGH
edges of the signal with the provided cycle time (1121/1).
The cycle time is entered in integer numbers (1 ms, 2 ms, 3 ms, ...).
1) Designation for the synchronization via system bus (CAN)
2) Designation for the synchronization via terminal
Code
Value Function
C1121/1 1 ... 13 ms Definition of the cycle time of the sync telegram (sync signal).
A parameterization is required only for the slave.
l C1120 = 1 (CAN sync)
– Time between two sync telegrams of the master. Adapt the time to the master SYNC. C0362 displays
the time (CAN sync cycle)for the slave. Set the value in C1121/1 smaller than the value in C0362.
l C1120 = 2 (terminal SYNC)
– Time between two sync signals of the master to X5/E5. Adapt the time to the master SYNC.Set the
value in C1121/1

cycle time of the master.
Interpolation cycle time (INTPOL. CYCLE)
The FB interpolates the input signals (C1124, C1125, C1126)between the sync telegrams and sync
signals and transmits them to the corresponding output. This means that an optimized signal shape
with regard to the internal processing cycle is achieved (e.g. reduction of signal step changes in the
output variables when using long sync cycles).
The interpolation is restarted with every sync signal (LOW-HIGH edge).
Code Value Function
C1121/2 1 ... 13 ms Definition of the interpolation cycles / steps
l C1120 = 1
– C1121/2 has no effect
– The interpolation cycles are derived from the sync cycle (C1121/1).
l C1120 = 2
– The interpolation cycle can be selected independently of the sync cycle.
– Select the parameterization of C1121/2 according to the cycle of the process value input.
