Global Constraints
Global constraints specify the minimum and maximum values associated with demands issued to the servo
control loops. In the case where a particular limit is not enabled, its global limit is set to the maximum internally
representable value.
The full set of adjustable constraints is listed below, and each of these constraints is
enabled by setting its associated bit to 1 (ON) in the Global Constraints Enable Flag (P-0-0099 / 32867). The
values residing in the following list of IDN’s, if so enabled, will be applied to constrain their associated demands;
Global Constraints Enable Flag
Global Maximum Position Constraint
Global Minimum Position Constraint
Global Maximum Velocity Constraint
Global Minimum Velocity Constraint
Global Acceleration Constraint (positive velocity)
Global Acceleration Constraint (negative velocity)
Global Deceleration Constraint (positive velocity)
The AMD2000 used fixed integer representations internal to the drive, and these make scaling of these variables quite
important. Therefore even if the user hasn’t specified a constraint, there is always a global constraint due to the size of variable
that can be represented.
