Chapter 1 Detail Drive Configuration and Operation
Sync Generator The sync generator can be used to synchronize a parameter and delay it one scan.
This can be used in conjunction with SynchLink (Refer to SynchLink on page
160 for more information).
Configuration:
• Parameters 788 [Xsync In 1] and 789 [Xsync Out 1] can be used to
synchronize a Dint parameter.
• Parameters 790 [Xsync In2] through 792 [Xsynch Out 2 Dly] can be used
to synchronize a Dint parameter and delay it one scan.
• Parameters 793 [Xsync In3] through 795 [Xsynch Out 3 Dly] can be used
to synchronize a floating point parameter and delay it one scan.
• Parameter 787 [Xsync Gen Period] sets the scan time of the synch
generator. The following options are available:
The default setting is 1 = “4 msec”.
Test Points Test points are used to monitor values in the drive for diagnostic information.
• [xxxx TP Sel] selects a value to monitor for diagnostics.
• [xxxx TP Data] shows the value selected by [xxxx TP Sel].
0 = 2 msec 3 = 16 msec
1 = 4 msec 4 = 32 msec
2 = 8 msec
