Content	Functional Example No. MC-FE-I-001-V11-EN 397 Ex. No. Behavior when Emergency Stop is issued Button S3 ( Emergency Stop ) is used to issue an Emergency Stop command. This initiates that the drive is shut down ac- cording to stop Category 1 in compliance with EN 60204-1. ■A 0 signal is entered, via the enable contact of safety com- bination A1, at contact X101.X (OFF3) of the drive. The drive is immediately braked down to 0 speed and the pulses are cancelled. At the same time, the drop-out delay of timer relay K2a and the delay time of the safety relay A1 are started; the drive must have come to a standstill before they expire. ■The internal safety relay of the drive is no longer energized after the drop-out delay time of time relay K2a has expired (1st shutdown path!). ■After opening the safely delayed enable contact of safety combination A1, line contactor K1 is no longer energized and the drive is electrically isolated from the line supply (2nd shutdown path!). ■The checkback signal from line contactor K1 is monitored in the on circuit of safety combination A1. If the contactor does not drop-out due to an erroneous function, a restart after Emergency Stop is prevented. Behavior when the protective doors are opened Button S1 ( Off ) requests that the protective doors are opened. This initiates that the drive is shut down according to stop Category 1 in compliance with EN 60204-1. ■Contactor K3 is longer energized. A 0 signal is entered, via its contact (NO contact), at contact X101.X (OFF3) of the drive. The drive is immediately braked down to 0 speed and the pulses are cancelled. At the same time, the drop-out delay of time relay K2a is started and before this time has expired, the drive must have come to a standstill. ■After the drop-out delay time of time relay K2a has expired, the internal safety relay of the drive is no longer energized (1st shutdown path!). At the same time, the latch (tum- bler) Y1 of the protective doors is opened. ■When the protective doors are opened the safety monitor- ing A2 of the safety circuit is interrupted. Before the selected delay time of safety combination A2 has expired, the internal safety relay of the drive must have already dropped-out. Its checkback signal contacts X533.1/2 indi- cate that the drive is in a safe condition. ■After the selected delay time has expired, the safely delayed enable contacts of the safety combination A2 open. ■If the internal safety relay of the drive is functioning cor- rectly, its checkback signal contact X533.1/2 is closed, line contactor K1 does not drop-out. If the internal safety relay does not function correctly, its checkback signal contacts X533.1/2 are not closed, line contactor K1 drops-out and isolates the drive from the line supply (2nd shutdown path!). Powering-up the drive The drive can be started when the protective doors are closed and Emergency Stop button S3 is released. ■When pressing button S2 ( On ), safety combination A1 is brought into the operational state. The coil of latch (tum- bler) Y1 is no longer energized, the protective doors are interlocked. Safety combination A2 is again in an opera- tional state. Line contactor K1 is energized. ■Contactor K3 is energized and latches and at the same time, time relay K2a is energized. The integrated safety relay is energized, a 1 signal is entered at contact X101.X (OFF3) of the drive. The drive restarts. 1.1
