External speed correction
When the Synchro function is not used, you can use External speed correction.
Parameter
SPD CORR PTR defines the correction by writing it to signal
SPEED CORR BUFF. This speed correction bypasses internal ramps. The speed
correction value is added to the speed controller.
Example:
To make an external device control the follower speed reference, for
example, through analogue input AI3, connect it to be the source for the reference:
SPD CORR PTR = 09.03.00 (
The figure below illustrates the operation of the function.
