9400 with SM301 - Safe stop 1 and implementation of a safe brake (two-channel) - performance level e
Function: When the safety function is requested, the motor is stopped according to stop category 1 of EN 60204-1.
For two-channel brake control with the SM301, you need two coupling relays. Use positively driven relays (e.g. Wago 788-384). To check if the relays work correctly, the feedback contact must be connected to a safe input of the SM301. Then, the discrepancy time of the two relays (K3 / K4) is monitored via the safe input I3.
Under normal operating conditions, the two brakes are operated via the 9400 application and the two auxiliary relays K1 and K2. To test the brakes independently of each other, they are separately released and the applied torque of the engaged brake is measured. The brake test is carried out via DIGIN 2 every time the LS_SpeedFollower is enabled.
Safety information / disclaimer:
The safety application and parameterisation notes are examples of possible subfunctions in machines.
The T10D value according to DIN EN ISO 13849-1, Annex C.4.2 is only indicated if a B10D value is available and the operating time is less than 20 years. Commissioning is prohibited until the machine has been checked in accordance with the regulations set out in the relevant EU directives / national laws. The safety instructions contained in the technical documentation must be observed. Using the examples does not exempt the user from careful project planning.
