B&R has equipped the ACOPOS P3 servo drive with safe torque determination. This allows the use of numerous safety functions that previously would have required an external sensor. The cost of machinery directive compliance is reduced.
Safe torque determination is based on an internal current measurement and enables the safety functions Safely Limited Torque (SLT), Safe Speed Observer (SSO) and Safe Brake Test (SBT). The functions are suitable for applications up to SIL 2 / PL d / Cat. 3.
