Defines lower threshold below which TACCMIN and TDECMIN are not affection the motion anymore. If actual values of acceleration (or deceleration) time is below this limit the whole excitation-limiting algorithm (TACCMIN & TDECMIN) is switched off.

CAUTION.svgCAUTION
Value of TSHORT is compared to acceleration/deceleration time only and not to the whole duration of movement. Therefore long movements with long cruise-velocity phase and short acceleration/deceleration times could trigger the switching-off the excitation-limiting algorithm. Use small values (1-4ms) for best results.
NOTE-Info.svgNOTE
Setting one of TACCMIN, TDECMIN or TSHORT to 0, disables the whole timing feature (excitation-limiting algorithm) altogether
