Cycle time setpoint for device synchronisation
• Time interval at which the phase control loop (PLL) in the inverter expects the synchronisation signals.
• The cycle time setpoint must be set according to the cycle of the respective synchronisation source.
Note:
• Only integer multiples of 1000 μs can be set.
• Intelligent communication modules usually define the cycle time setpoint derived from the bus cycle. In this
case, a manual change is not possible.
Example: For the CAN bus, a distance of 2 ms has been set between two synchronisation signals. If the CAN bus is
to be used as synchronisation source, a synchronisation cycle of 2000 μs must be set in C01121.

Phase position for device synchronisation
• The phase position determines the zero-time of the internal system cycle with regard to the synchronisation
signal (bus cycle). Since PDO processing is an inherent part of the system part of the application, the instant of
acceptance of the PDOs is postponed as well by a changed phase position.
• With a setting = 0, the system cycle starts simultaneously with the synchronisation signal.
• With a setting > 0, the internal system cycle starts earlier by the set time with regard to the synchronisation
signal (the phase position acts negatively).
• Intelligent communication modules define the optimal time with activated synchronisation by themselves. In
this case, a manual change is not possible.
• The decisive factor for defining C01122 is the time where all nodes are provided with valid PDOs.
Example: If the phase position is set to 550 μs, the system part of the application starts 550 μs before the arrival of
the synchronisation signal.

Time slot for monitoring the synchronisation signal or the phase position
• The synchronisation signal or the current phase position must be within this time slot around the corresponding
expected value (C01122
).
• With the setting "1000 μs" there will be no monitoring.
