Set Error Limit

C Definition

void dms_SetErrorLimit(long NodeNumber, long GroupNumber, double Param)

Pascal Definition

procedure dms_SetErrorLimit(NodeNumber:longint; GroupNumber:longint; Param:double);

Description

Set Error Limit is used to describe how far a physical axis's Actual Position can lag behind the Commanded Position without that lagging being considered an error. In the ideal case the motor's Actual Position exactly follows the Commanded Position but system dynamics and transient response of the motion control law often make this goal impossible. However, the error can be minimized for profiles without acceleration. Systems which undergo high acceleration and deceleration are likely to incur hysteresis if the power system saturates. If the difference between the Actual Position and Commanded Positions exceeds the Error Limit that was set, the axis will perform a Motor Off.

Escapes

The Set Error Limit command does not produce any escapes.

Note that the EscapeResult parameter must be preset to 0 before making the call or the routine will not run
