MC-Basic:axis.TIMEOFSHORTMOTIONS

From SoftMC-Wiki
Jump to: navigation, search
Language: English

Defines the lower threshold below which TACCMIN and TDECMIN no longer affect motion. If the actual values of acceleration (or deceleration) time is below this limit, the entire excitation-limiting algorithm (TACCMIN and TDECMIN) is switched off.

CAUTION.svgCAUTION
The value of TSHORT is compared to acceleration/deceleration time only, and not to the entire duration of movement. Therefore, long movements with a long cruise-velocity phase and short acceleration/deceleration times could trigger the switch-off of the excitation-limiting algorithm. For best results, use small values (1 to 4 ms).


NOTE-Info.svgNOTE
Setting one of TACCMIN, TDECMIN or TSHORT to 0, completely disables the entire timing feature (excitation-limiting algorithm)
