Omron has launched a series of AC servomotors and drives with built-in safety functions that can help prevent machine stoppages and achieve zero-loss production due to synchronized emergency stops.

The 1S Series drives span ratings from 200 W to 3 kW and the motors incorporate 20-bit high-resolution absolute multi-turn encoders. These systems can provide 350% of peak torque and the drives need just one Source: Omroncable connection: power, encoder and brake signals are all carried by pre-assembled cables with IP67 connectors.

The drives are claimed to ensure safety and to minimize downtime and production losses. The machine can slow down to a safe speed without stopping production if an operator on a manufacturing line is carrying out maintenance or making adjustments. If the operator needs to intervene in the process, all axes can be stopped with the Safe Stop functionality and kept at a safe standstill with the Safe Operating Stop mode.

Integrating a wide choice of safety functions (STO, SS1, SS2, SOS, SLS, SLP, SDI and SBC) also cuts costs, wiring complexity and the need for extra components. The drives support Safety over EtherCat (FSoE), reducing wiring and maintenance while conforming with PLe/SIL 3 performance levels.
