What is the difference between the I/O mode and separate mode in the Altivar71 drive.
The difference between the I/O mode and separate mode is the means to control the drive:
- In separate mode the reference and the command can be sent via 2 different channel but follow the DriveCom chart. For example you have to do a sequence before start the drive i.e. to send CMD=16#0006, then CMD=16#0007 and then CMD=16#000F.
- In I/O mode only one bit of the command word can run the drive. In this mode we are working with a virtual I/O terminal. Each bit of the command word can be used to enable a function (Start, stop, forward, reverse...).
