EachVFD having the following configuration: Control unit CU320, 6SL3040-0MA00-0AA1 Motor module, 6SL3325-1TG41-3AA0 1200kW Terminal module TM31, 6SL3055-0AA00-3AA0 Sensor Module SMC30, 6SL3055-0AA00-5CA2 A motorised circuit breaker connects the motor module to a common DC-bus. For reading motor speed,a standard incremental HTL pulse encoder is connected toterminalsonSMC30. We are using FW2.5 SP1 All VFD's are controlled by a common 317-2DP CPU -- The requested response to emergency stop is: "When emergency stop button is activated the VFD should ramp down to stop as fast as possible and hold the load" The emergency stop system should be at least Category 2 according to EN 954-1 I guess that Safe Stop 2 with transition to Safe Operational Stopwould give the requested response. I have read about the functionality in the "Safety Integrated Function Manual", but still have some questions: 1: Doesthe above mentioned Sinamics components comply with the requirements for using SS2 & SOS? 2: Do I need to purchase an additional license to use the extended safety function? 3: I guess I will need to use the TM45F for the EmStop inputs, correct? 4: What about the actual speed? Will the encoder configuration comply with the requirements for using SS2 & SOS? Best regards Knut

These functions are only available in the safety extended functions. These functions can either be used with a TM54F or via PROFIsafe, and a safetylicense/axis is required. However the safety extended functions are not available yet for chassis drives, we hope it will come soon this year. Another requirement is a safe evaluation of the encoder signals, which can momentarily only be done in a 1-encoder system with 1Vpp sin/cos encoders (with HTL encoder it won't work!)

Wir haben eine neue Baureihe die auch im Hinblick auf die neue EN 13849 einige interessante Features bietet.

vadak Posts: 12 Rating: (0)	Hello, I have the samewinch application as thethreadcreatorwith some changes. I'm using a SMC20 encoder module with a 1Vpp Encoder and 132kW motor module. Do you know if the SS2 function has been implementedin the chassis drives yet? Best regards vadak
