附原文：
When the SmartStep engine detects that a CV will violate limits, it attempts a series of correcting moves to avoid the violation. Correcting moves can be made by MVs that belong to groups in TEST, TEST NO_PULSE, or SUSPEND modes.
The STCMFLAG parameter is used to specify the number of consecutive correcting moves the SmartStep engine should attempt before switching to CORRECTING or REPOSITION mode. A correcting move is implemented in the same way that a user requested target change is implemented.
Properties of correcting moves include the following:
?The move plan for the correcting move will not violate minimum or maximum movement criteria (STMVMAXU, STMVMAXD, STMVMINU, STMVMIND).
?No high or medium frequency pulses are superimposed onto a correcting move plan.
?The MV undergoing the correction move will show STEPPING until it reaches its new target and then it will return to the state it had before the move was initiated.
?If the engine decides to move a currently stepping MV, the correcting move plan will replace the test move plan, but the step duration counter will be left alone.
When a correcting move is needed, the SmartStep engine considers a variety of factors to determine which MV to move. MVs that are currently idle (STMVSTATUS = SUSPEND, TEST, STEP NEXT, SKIP) are considered first. Both the LP cost (CST) and LP criterion (LPCRIT) are also taken into account. Using the LP cost and LP criterion allows the engine to preferentially choose the MVs based on engineer tuning.
