The Safe Motion Monitoring and Control is the reliable monitoring of machine movements. Many certified drive safety functions optimize the interplay of human and machine. Direction, speed and position are reliably monitored in mobile and stationary machines. This means you can make continuous processes a reality while reducing machine downtime.

The Standstill Monitor MOC3ZA is a safety device for machine drives and serves to protect against dangerous movements. It also measures the residual voltage meaning that no additional sensors are required for the purpose of standstill monitoring. This renders the device suitable for applications with three-phase, single-phase and direct current motors. For optimum integration into the work environment the Standstill Monitor MOC3ZA is available in three different versions – depending on the supply voltage. The positively guided safety contacts enable the device to be connected to all of SICK's safe control solutions.
