The Acopos drive system is based on Powerlink Safety. Enabling functions such as safe limited speed is done directly over the network. The information is collected from its source via safe digital inputs and outputs, then distributed to the corresponding sensors and actuators, in this case the drive, via the SafeLogic central processing unit. Safety in the Acopos drive system comprises the following functions according to Cat. 3, EN 954-1: uncontrolled and controlled stops; safe stop and safe operation halt; safe limited step measurement and safe limited absolute position; safe limited speed; safe rotational direction.B&R Industrial Automation Corp. www.br-automation.com770.772.0400
