Page 7: Functions And Features
3 Functions and features 3.1 General function description The device is a two-channel pulse evaluation system for safe underspeed detection� To do so, it receives the pulse sequences from the pulse pick-ups connected to the inputs� The device calculates the resulting frequency� By continuously comparing the input frequency (actual value) and the switch point (target value) the device promptly detects underspeed of the set switch point�... -
Page 8: 3�3 Switching Function "Underspeed
3.3 Switching function "underspeed" The output relays de-energise when underspeed occurs (frequency FuH has been reached)� The relays energise again when the input frequency exceeds the set switch point Fu� f in Safety output Switching characteristics of the current paths (safety-related outputs) Frequency underspeed (= set switch point) Fuh: Frequency underspeed –... -
Page 9: 3�6 Start-Up Delay

Page 14: 5�2 Automatic/Manual Mode Selection
5.2 Automatic/manual mode selection If underspeed is detected, the current paths open and the drive is switched off� The manual operation can prevent the current paths closing automatically as soon as the input frequency exceeds the Fu value again� The operating mode is selected via the circuitry of two input terminals Y5 and Y6� 5.2.1 Automatic operation In this operating mode the device compares the input frequency with the set switch point�... - Page 15 Automatic operation (circuitry of the inputs Y5 and Y6) The automatic operation mode is implemented by connecting input Y5 to Y1 (pulsed test signal) and input Y6 to + 24 V DC� If the device detects an error, it returns to the safe state (→ 3.2 Safe state of the output relays (failsafe state))�...
