7.5.22 Control Techniques objects
The Control Techniques objects (classes 0x64 to 0x69) allow access to all drive and
option module parameters. The class instance number is used to reference the drive or
option module menu number (except menu 0) and the class attribute number
references the parameter within that menu.
For example, the drive parameter Percentage Load (0.04.020) would be accessed as
class 0x64, instance 0x04 and attribute 0x14.
An instance value of 0 is invalid therefore to allow access to menu 0 parameters, the
instance value 200 (0xC8) must be used.
The number of instances and therefore the number of menus for each class depends
on the destination device. If the drive is the destination then the number of menus will
depend on the drive operating mode. If the destination is one of the option slots (or
onboard Ethernet interface) then the number of menus depends on the type of option
module fitted (or the onboard Ethernet interface).
Six individual classes are provided, the following table shows the classes used when
accessing the drive or option module parameters.
