Content	Functional Example No. MC-FE-I-002-V11-EN 413 Ex. No. Behavior when Emergency Stop is issued Emergency Stop is initiated using button S3 ( Emergency Stop ). This initiates that the drive is shut down according to stop Category 1 in compliance with EN 60204-1. ■A 0 signal is entered at contact 65 (controller enable RF) of the drive via the enable contacts of safety combination A1. 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, the internal line contactor of the rectifier unit is no longer energized and the drive is electrically iso- lated from the line supply (2nd shutdown path!). ■The checkback signal of the internal line contactor of the rec- tifier unit is monitored in the on circuit of safety combination A1. If the contactor does not drop-out due to an incorrect function, then the drive is prevented from restarting after an Emergency Stop. 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 no longer energized and a 0 signal is entered at contact 65 (controller enable RF) of the drive via its contact (NO contact). 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 AS1/2 indicate 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 contacts AS1/2 are closed and the internal line contactor of the rectifier unit does not drop-out. If the internal safety relay does not function cor- rectly, its checkback signal contacts AS1/2 are not closed, the internal line contactor of the rectifier unit 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. The internal line contactor of the rectifier unit is energized. ■Contactor K3 is energized and latches and at the same time, time relay K2a is energized. The integrated safety relay is energized and a 1 signal is entered at contact 65 (controller enable) of the drive. The drive restarts. 2.1
