Example configurations:
Example 1: PLC operates with 1 ms cycle time
The 1 ms cycle is supported by the inverter. Here the value 1 can be set as the
factor for the Sync Unit Cycle.
The related operation mode is: DC enabled (multiplier = 1)
Example 2: PLC with 500 µs cycle time
The fastest cycle time in the inverter is currently 1 ms. For this reason the inverter
cannot synchronize with the SYNC 0 signal if the SYNC 0 cycle time is 500 µs.
In this case the operation mode with the multiplier = 2 must be activated.
The cycle time for the controller is then still 500 µs.
The SYNC 0 signal then has a cycle time of 500 µs * 2 = 1 ms. With this
configuration it must be noted that the slave only receives every second output
value calculated by the PLC and only collects every second input value.
4:Factor Here the factor used to calculate the cycle time for the
SYNC 0 signal based on the Sync Unit Cyclecan be
selected.
Normally the factor 1 is set here so that the cycle time for
SYNC 0 is the same as the Sync Unit Cycle.
5:Enable SYNC 0 Activates the synchronization signal SYNC 0. The slave
synchronizes to this signal. For this reason the signal must
be activated here.
6:Shift Time This value defines the slave user shift time.
Normally the value is = 0.
Information
The inverter will not change from PREOP to SAFEOP if a valid cycle
time for the SYNC 0 cycle is not set with synchronization activated.
In case of problems with the activation of the synchronization, the
cause of the error can be read in the parameter A261 element.
