Overview of the safety options

In the device, the STO safety sub-function is always available and can be extended with the following 3 safety options.

  • MOVISAFE® CSB51A safety option
  • The MOVISAFE® CSB51A safety option provides the STO and SS1-t safety sub-functions. The functions can be controlled via safe communication.
  • MOVISAFE® CSL51A safety option
    • 4 safe single-channel digital inputs or 2 safe two-channel digital inputs
  • The safety option MOVISAFE® CSL51A provides the safety sub-functions STO and SS1-t. When using a safe built-in encoder, the safety sub-functions SS1-r, SLS, SSM and SDI are available for motion monitoring. The functions can be controlled via safe communication and safe digital inputs.
  • MOVISAFE® CSS51A safety option
    • 4 safe single-channel digital inputs or 2 safe two-channel digital inputs
  • The MOVISAFE® CSL51A safety option provides the safety sub-functions STO and SS1-t. When using a safe built-in encoder, the safety sub-functions SS1-r, SLS, SSM, SSR, SLI and SDI are available for motion monitoring. The safety sub-functions can be controlled via safe communication and safe digital inputs.
