3.3 adt8840a_set_speed( )
Name int adt8840a_set_speed(int dev_num,int axis, long Value)
Definition Set drive velocity
Input parameter
dev_num: device number
axis: axis number (1 - 4)
Value: V’s value (1 - 2000000)
Output
parameter
None
Return value 0: execution OK; -1: transmission abnormity; -4: disabled device interface
Note
It is value that reaches the set-speed domain in acceleration/deceleration drive. The
set-speed drive starts from this value. If this value is set below the start velocity, the system
will not perform acceleration/deceleration drive, but set-speed drive from the very
beginning.
3.4 adt8840a_set_command_pos( )
Name int adt8840a_ set_command_pos(int dev_num,int axis, long Value)
Definition Set number of logic-position counter
Input parameter
dev_num: device number
axis: axis number (1 - 4)
Value: scope (-2147483648 ~ [phone])
