A.1.8.1 Settings
Setting time synchronization
1. Using p3100, changeover the time format from operating hours into the UTC format (see
"Changing the time format").
2. Set the synchronization technique:
– Basic synchronization (p3103 = 2)
– Time synchronization with ping compensation (p3103 = 0)
3. Using p3104, set the ping source:
– If you are working with one of the telegrams 390, 391 or 392, then the source of the ping
(p3104) is internally connected with bit 1 of the CU control word (DO1:CU_STW.Bit1).
In this case, parameter p3104 is blocked.
– If you are using a free telegram (999), interconnect the ping source (p3104) via BICO
in the control word.
– If you are working with CANopen, interconnect a free bit in the CANopen control word
with p3104 via a BICO connection.
Result:
After time synchronization, the current time is obtained from the time transferred by the time
master plus the delay time associated with the transfer (ping-snap time).
The actual UTC time is displayed in the drive system using r3102.
At certain intervals, synchronization (according to the same technique) is repeated (depending
on the setting in the time master).
If a previously defined tolerance window is exceeded, then alarm A01099 is output. The
tolerance window for time synchronization can be defined using p3109. If alarm A01099
occurs, then generally the synchronization interval is to large.
In this case, reduce the synchronization interval in your control system.
Changing the time format
The time format is entered via parameter p3100. This parameter cannot be changed online
To change the value, proceed as follows:
1. In STARTER, using the "Project > Connect to target system" function activate the ONLINE
mode.
2. Upload using the "Target system> Load > Project to PG" function.
3. In STARTER, using the "Project > Disconnect connection to target device" function exit the
ONLINE mode.
4. Offline, in the expert list of the control unit, make the setting p3100 = 1.
