Homing Once is Enough

B&R Industrial Automation

New safety functions for B&R ACOPOSmulti servo drives offer many advantages, including no longer having to home robots after a restart.New safety functions for B&R's servo drive family

With SafeMOTION Release 1.9, B&R has updated the safety functions for the 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.

In order to obtain a safe absolute multi-turn position, homing used to be necessary each time an axis was restarted. In some situations, this can require considerable effort, especially for complex multi-axis systems. The Remanent Safe Position (RSP) function allows SafeROBOTICS SLS, SLP and SLO functions to be used without homing after every power-on cycle.
Closer to the limit
The Safely Limited Acceleration (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 Saf-eROBOTICS function can thus be configured closer to the point where there is real danger.
Transfer parameters easily
When commissioning some machines, it is necessary to make machine-specific settings for certain parame-ters, such as the homing offset or the unit system. You can now use the machine options function to selec-tively transfer the safety parameters from the functional application to a SafeMOTION module. These safe machine options can be used to update parameters, for example via the HMI application on the operator panel.
