A1-07: DriveWorksEZ Function Selection
Enables and disables the DriveWorksEZ program inside the drive.
DriveWorksEZ is a software package for customizing drive functionality or adding PLC functionality by the interconnection
and configuration of basic software function blocks. The drive performs user-created programs in 1 ms cycles.
Note: 1. If DriveWorksEZ has assigned functions to any of the multi-function output terminals, those functions will remain set to those terminals
even after disabling DriveWorksEZ.
2. For more information on DriveWorksEZ, contact a Yaskawa representative.
