Updates increase servo drive safety

With the release of SafeMOTION version 1.9, B&R has updated the safety functions for its ACOPOSmulti servo drive family.

In addition to two new functions – Remanent Safe Position (RSP) and Safely Limited Acceleration (SLA) – this update also introduces machine options for SafeMOTION parameters, and improves both system availability and user-friendliness.

The RSP function allows SafeROBOTICS SLS, SLP and SLO functions to be used without homing after every power-on cycle. This eliminates the sometimes considerable effort required to obtain a safe absolute multi-turn position each time an axis was restarted.

The SLA function monitors the acceleration or deceleration of an axis. If the limit being monitored is exceeded, the SafeMOTION module goes into an acknowledgeable error state. Using the SLA safety function for coupled axes, for example, makes it possible to significantly reduce the maximum remaining distance an axis will move in the event of an error. The speed limit set in the SLS SafeROBOTICS function can thus be configured closer to the point where there is real danger
