Speed compensated stop
Speed compensation stop is available for example for applications where a conveyer
needs to travel a certain distance after receiving the stop command. At maximum
speed, the motor is stopped normally along the defined deceleration ramp, after the
application of a user defined delay to adjust the distance traveled. Below maximum
speed, stop is delayed still more by running the drive at current speed before the
motor is ramped to a stop. As shown in the figure, the distance traveled after the stop
command is the same in both cases, that is, area A + area B equals area C.
Speed compensation does not take into account shape times (parameters
). Positive shape times lengthen the distance
traveled.
Speed compensation can be restricted to forward or reverse rotating direction.
Speed compensation is supported in both vector and scalar motor control.
