2 Product description of safety module CAMC-G-S3
2.5.9 SSR – Safe Speed Range
The function described here implements the safety function SSR according to EN
61800-5-2.
Use the "Safe Speed Range" (SSR) function if you wish to ensure in your application that
the motor speed remains within specified limit values.
The following parameterisation means that the Safe Speed Function SSF corresponds to the SSR safety
function (with immediate speed monitoring without slowdown ramp):
