A-7-4 Performance Improvements for Unit Version Upgrades
This section introduces the functions for which performance was improved for each unit version of the
CPU Unit and for each Sysmac Studio version.
*1 The performance improvement applies only to an NJ301- CPU Unit. The maximum number of vari-
ables with a Retain attributes for the NJ501- is 10,000.
*2 This is the total for all axis types.
*3 The performance improvement applies only to an NJ301- CPU Unit. The maximum numbers of con-
trolled axes for the NJ501- are as follows:
NJ501-5: 64 axes, NJ501-4: 32 axes, and NJ501-3: 16 axes
*4 There is no change in the maximum number of used real axes.
