Basic Pack Profile
For simple servo drives and frequency converters, a basic profile was defined. This profile consists of Communication Class A covering the following functions:
-- ring configuration for phase run-up & timing
-- cyclic communication with standard telegrams
-- diagnostic information
-- status and control signals
Structure of Basic Pack Profiles
The Basic Pack Profile A defines the parameters that are required to send cyclical position command values to a simple servo drive. The data scaling of the position command values is rotational, measured in degrees, and is processed either in an absolute or a modulo value. The position loop is closed in the drive; the position feedback value is transmitted back to the control. The profile allows limit values to be defined for torque/force, velocity and position. The scaling of velocity data is in revolutions per minute. Torque and force data is scaled in percentage.
The Basic Pack Profile B defines the parameters that are required to send cyclical velocity command values to a frequency converter. The profile allows limit values to be defined for torque/force and velocity. The scaling of velocity data is in revolutions per minute. Torque and force data is scaled in percentage.
