B.3.16.20 DS402 Profile Velocity Mode
In this mode, a target velocity is input to a profile generator. It generates a velocity demand profile for the
velocity control loops, with further inputs to the profile generator limiting its output.
INPUT PARAMETERS → This parameter allows the user to setup the input parameters of profile
velocity mode. The parameters are:
• Target Velocity → Input/Set-Point for velocity, in velocity units.
• Max Profile Velocity → Maximum speed allowed during a profile move, in velocity units. This
value is limited to the lower value of the following 2 parameters (Max Load Speed and Max
Motor Speed)
• Max Load Speed → Maximum speed of the system, used in the velocity loop.
• Max Motor Speed → Maximum allowable speed of motor, in rpm.
• Profile Acceleration → Used to define acceleration of moves, in acceleration units.
• Max Acceleration → The max acceleration can be used to limit the profile acceleration, in
acceleration units.
• Motion Profile Type → Used to select the type of motion profile to perform. Only linear ramp
(trapezoidal profile) is implemented.
FEEDBACK PARAMETERS → This parameter allows the user to see the value of the three feedback
parameters. The parameters are:
• Velocity Sensor Actual Value → Value read from resolver in (incs/sec).
• Velocity Demand Value → Output of velocity demand function, in velocity units.
• Velocity Actual Value → Sensor Value scaled to be in velocity units.
VELOCITY CONTROL PARAMETERS → This parameter allows the user to set up the velocity control
parameters. The parameters are:
• Velocity Window → Limits (in velocity units) within which target velocity reached bit can be
set, in status word.
• Velocity Threshold → If velocity actual value is less than or equal to this value (in velocity
units), Speed=0 bit can be set, in status word.
STATUS WORD BITS → This parameter allows the user to see the status word bits.
• Target Reached → Indicates that the target velocity has been reached, within the velocity
window.
• Speed=0 → Indicates that the speed is at zero (less than the velocity threshold).
CONTROL WORD BITS → Allows the user to set/clear the halt bit.
