Specialized in safety controls for drive monitoring

 

Due to technological advances in drive technology, even entry-level drives such as stepper and EC motors increasingly require functions like STO (Safe Torque Off) and SLS (Safe Limited Speed). Drive manufacturers are also seeking comprehensive safety solutions that go beyond mere drive monitoring and cover all safety circuits.

Renowned drive manufacturers worldwide rely on DINA’s safe drive monitoring solutions. While our sensorless solutions are the ideal choice for cost-optimized drives, we complement this portfolio with encoder-based safety controllers for more complex systems. These enable the flexible and precise integration of additional safety functions.

Encoder-based monitoring

Sensorless monitoring

 

The safety switching devices monitor speed, direction of rotation and standstill precisely without any sensors. This allows safety functions to be integrated into drives in a particularly cost-efficient manner. The modules meet the certified Performance Level e or SIL 3.
