Changed functions Descriptions
Positioning start No.
No. 9004 (Multiple axes simultaneous start control) is added.
Nos. 7004 to 7010 (block start designation) and 8000 to 8049 (indirect
designation) are deleted.
Block start data
With the QD75, the number of blocks is changed to 5 (7000 to 7004). (With the
A1SD75, this data is called "positioning start information".)
Special start data "Simultaneous start" The simultaneous start is possible up to 4 axes.
List of errors/warnings
Refer to the following "Error code comparisons" and "Warning code
comparisons".
Start history
The configuration of "start information" and "start No." is changed so that the start
No. can be directly checked.
Synchronization flag (X1)
When the PLC CPU starting method is set to asynchronous, interlock is
established with the synchronization flag (X1) signal.
Basic parameter 1 "
Pr.5
Pulse output mode"
When the PLC is turned ON or the PLC CPU module is reset, the valid value is
only the first value after the PLC READY signal (Y0) turns from OFF to ON.
