  • Page 64: Switching Energy / Operating Frequency

    Technical specifications Disengagement time The disengagement time is not influenced by DC or AC switching operations. Engagement time The transition from brake-torque free state to holding braking torque is not free of time lags. For emergency braking, short engagement times for the brake are absolutely essential. The DC switching in connection with a suitable spark suppressor is therefore to be provided.
