CHANGE DYNAMICS function

Function block for MP2000 series

Function Block Summary

This function block sets acceleration, deceleration, S-Curve and the speed. Each parameter is set in the
first execution scan.

Function Block Operation Notes

• Rising edge of EXECUTE input initiates block operation, and all block input

values are read once.

• To use the function block, the EXECUTE bit must be held ON. If the EXECUTE

bit goes off during operation, the block will finish move but all outputs will be set
to zero.

• The

RUNNING

output bit will be held high parameter change is completed,

EXECUTE

goes low or an Error occurs.

• If any of the inputs (absolute value) are greater then the Maximum value in the

RDA an Error will occur.

• When parameter setting is completed, the DONE output is turned on.

• Each value (SPEED, ACCEL, DECEL, and SCURVE) is also set to the

corresponding RDA.

• S-Curve value is for the running average filter. S-curve outputs literally “S"

reference on acceleration and the deceleration.
